ABSTRACT: The present paper deals with the measurement of the cross
sections and of the angular distributions of the reaction
T(p,n) in tile interva'l 7 - 12 Tilev of proton energies. 1"'ore-
over, the authors tried to measure the polarization of the
neutrons in this reaction. A solid tritium-zirconium tar-j-et
(thickness 20 g) was bombarded by protons accelerated to
12 Mev in a cyclotron. The neutron flux was measured.by a
telescope consisting of 4 proportional counters and also
by a spectrometer. The cross sections are meaoured with a
precision of I ejo. The first diagram shows the results of the
measurement of the cross section under the angle 00 and
previously published results of the measurements in the energy
interval of I - 7 Mev '. The cross section is approximately con-

ABSTRACT: By means of a method workbd out by the authors in their labors-
-7,
tory the spectra of tritons emitted dt'various angles betwe6li
7 and 1500 in-the (d,t) reaction were investigated for 20 Mev
deuterons which had been accelerated in a cyclotron. Calcula-
tion of angular diatribution-was carried out by means of
Butler's formula amended according to Newns (5); the triton
form factor was obtained from a paper by French. Results:
L17(d,t)Li6: figure 1 shows the characteristic shape of the
triton spectrum (in this case at 70); the spectrum hag 3
distinct maxima - the ground state and the two first excited
states (2.19 and 3.58 Mev); the levels with 4.5 and 5.3 Mey
are only very weakly developed. The continuous triton spectrum
to be investigated is explained as being due to a breakup

.,''Besides the two ground state maxima o .4 t
f L'5 and Li , the
spectrum has yet another weak maximum at 2. 19 Mev ~,ij. The width
of the LO ground level was determined as amounting to
(1.3�0.2) Mev. The continuous spectrum observed may be ex-
plained in different ways, as e.g. as the result of the re-
action L16(d,p)Li7#---3,.He4+ t. The angular distribution of this
reaction - if the U5 formed is in the ground state --is
shown by figu e 5; thg curve was again calculated according
to Butler. Be5(d,t)Be : The-spectrum has 2 distinct maxima,
the narrow, high one of the Bea-ground state, and the wide one
(width 1.3~+0.15 Mev)p which is barely half as high, of the
excited state with 2.9 Mev. Moreover, there is the possi'bil-
ity of the existence of peaks at 4.2, 4.9, 5.4, and 6 Mev;
a small but distinctly marked maximum is at 16.9 Mev.

given as 50 mb. The total measuring data of all reactions in-
vestigated are given by a table. The absolute error in arose
section measurement is given as amounting to +20 %. Generally
spoken it may be said that the probability of the formation
of excited states in the final nucleus decreases sharply with
increasing excitation energy. The authors finally thank
S. P. Kalinin for his interest in this'investigation, and
they also thank the cyclotron team under Yu. M. Pustovoyt for
carrying out the irradiation, and finally also A. I. Baz'
and D. P. Grechukhin for discussions. There are 8 figures,

TEXT: Measurements of fission cross sections for high-energy neutrons
are communicated in this "Letter to the Editor". The neutron source was
the reaction D(d,n)He3; the analysis was made by the time-of-flight
method, as it avoided some of the difficulties discussed in the intro-
duction. The deuteron energies were varied from 6.5 to 19.5 Mev
(En: 9-T - 21-7 Mev) by means of platinum foils. The energy spread of
the neutron was between 250 and 700 kev. All measurements were made at
an angle of 00 to the deuteron beam. The fission events were recorded
by means of a gas scintillation fission chamber (xenon) and a photo-
multiplier of the type P-33 (FEU-33). The pulses from the multiplier
were fed into a multi--channel time-of-flight spectrometers The results

TEXT: The authors report on experimental investigations of the (a,t) re-
action with Li7, Be9 and Na 23 with an a energy of 40 Mev in a wide exci-
tation energy range. The final nuclei Be a , B10 and Mg 24 were also obtain-
ed through (d,n) stripping reactions and (d,t) adhesion reactions. The
triton spectra, like in investigations of the (d,t) reaction, were de-
termined from the tritium activity which had accumulated on the foils 2
arranged around the target. Foils of the investigated element of 4'mg1cM
thickness served as targets. The results of these experiments are only
illustrated in diagrams. Fig. 1 shows the angular triton distribution;

PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki, 1960,
Vol. 39, No. 6(12), pp. 1612 - 1614
TEXT: For investigating the (d,pn) splitting mechanism the authors
selected the He4 nucleus, because on it the (d,2n) and (d,2p) reactions
have high thresholds and because at an energy of 20 Mev the
(d,pn) reaction is the only one that furnishes nucleons with continuous
spectrum. Spectra and angular distributions of the He4+d reaction at
20 Mev were investigated by means of photographic plates. The deuteron
energy of 20.2 Mev was determined from the range of the particles after
scattering in the emulsion. T~e plates were arranged at intervals of 15
within the region of 15 - 165 at a distance of 12.5 cm round a gas
ta~:get; their angle towards the direction of flight of the reaction
products was 80. During evaluation of the plates, such tracks were

The background within the range of the continuous spectrum was dalO%. Thp
results obtained are :,hown in diagrams; thus, Fig.3 ahows the spectrum of
the protons from tho reaction He4+d for various angles, and Fig.4 shows
the proton- and deuteron angular distributions for four processes. Whereas
the proton group from the reaction He4(d,p)He5 (ground state) with in-
creasing angle quickly loses intensity, and at 0 >500 amounts to less than
15% of the continuous one, and also the neutrons from the reaction
He4(d,n)Li5 are mainly observable under an angle of 00, the fraction of
protons of the continuous spectrum originating from (d,pn) reactions is
considerable, and the shape of their spectrum does not depend
essentially on the angle. The angular distribution of the protons of the
continuous spectrum is similar to that of the elastically scattexbd
deuterons and also the cross sections of the two reactions are similart

TITLEs The (d,t) Reaction. on Zirconium Isotopes
PERIODICAL: Zhurnal eksperimentaltnoy i teoreticheskoy fiziki, 1960,
Vol. 39, No. 6(12), pp. 1615 - 1617
TEXTs In order to study the effect produced by external neutrons, the
authors investigated the (d,t) reactions on Zr91,92,94, which have
1, 2, and 4 neutrons above the closed shell with N - 50. The triton
spectra were, like in earlier papers (Refs.1-3) determined according to
the P-activity of tritium. The tritons emitted from a target of 3-5 mg/cm
-were caught in piles of aluminum foils arranged under different angles at
a distance of 15 cm from the target. The deuterons were accelerated in the
cyclotron to 20 Mev. The targets were made from zirconium oxide, enriched
in Zr91 to 79-5%, in Zr 92 to 68.6%, and in Zr94 to 90.0%, respectively.
All three isotopes displayed the existence of two state groups - the first

corresponds to the ground state, the second to an excited state. The
angular distributions af these groups are shown in Fig.2 (upper rows
ground state). To the ground-state group there corresponds an 1 . 21 i.e.
to a d5/2 'tate, the excited group 1 = 1 and 4 (width - 2 Mev). One of thc~
groups corresponds to an ejection of neutrons from a closed shell with
neutron binding energies, which are appi:oximately equal and are about
11 - 13 Mev for all zirconium isotopes. In the Zr9o(d,t) reaction only
this group is to be observed; its intensity decreases slowly from
Zr90 to Zr94. The other group corresponds to an ejection of an external
neutron. The intensity of this group is almost proportional to the
number of super-magic neutrons. There are 3 figures and 4 references:

that the T(p,n)He reaction is a good source of polarized neutrons with
En - 8 Mev or more. The angular dependence of the polarization seems most
appropriate for an interference of the P 3/2 and P 1~,2states of the emitted

tion with Ep - 3 Mev; howeverg a resonance may also exist with higher E p

become considerable at Ep a 10 Mev2 which makes interpretation of polariza-

TEXT: The present investigations continue previous sNies (ZhETF 1959,
27, 54) which had show-a that in (d,t) reactions on Li 7 and Be9 the
excitation probability decreases rapidly with increasing level energy of
the terminal nucleus. The excitation spectrum is here much more compli-
cated than where only hole levels are excited, es neutrons may not only be
extracted from outer (2s and 1d), but also from full 1p, shells. The
triton spectra were obtained from the P activity of the resulting tritium
collected in Al foils. It was eliminated from the plates by heating and
conducted2 into a helium counter. F19(d,t)F 182 was investigated with a
0.4 mg/cM thick MgF2 target and an 8.2 mg/cM thick Teflon (CF2) target

Al target. The Teflon target was also used to study the C 12 (d,t)C 11 reac-
tion. The t-angular distributions were compared with results obtained
from the Butler theory. The strongest triton group consists of two
comlonents (1-0 and 1-1). The scheme producgd for P18 level agrees with
that of other authors. Fig. 6 shows the A12 level scheme obtained by
other authors together with transitions observed here. Tabulatid results
show that the (d,t) reactions on F19 and A127, like those on Li and Be9,
have a probability of excitation of the final nuclear levels which
decreases rapidly with increasing level energy. The reduced widths of
the 3-4 Mev levels are 3-10 times smaller than those of the ground state-
Those of 5-7 Mev have 20-30 times less probability of excitation than the
ground level. The 3.3-Mev Fla level (1.1) has negative parity and
comparatively high probability of excitation (width: O~73~) since a
neutron is torn out of the p shell. In A127; extraction of a neutron with
I - 2 is much more probable than one with 1 - 0, i.e., the inner neutrons
of A127 are mainly in the d-state with a small admixture of a-state.

TEXTt The article gives the most important data concernIng the cyclotron
of the Institut atomnoy energii im. 1. V. Rurchatova (Institute of Atomic
En6rgy imeni I. V. Kurchgtov), and some experiments are described. A
complete description of this cyclotron may be found in Ref, I
(L. M. Nemenov et al., Atomnaya energiya, II, No. 1, 36 (1957))- It was
constructed in 1947; in the following years, it was improved by focusing
the beam onto'a target at 12 m distance. In all operating conditions
(parameters are given in a table), the currents reaching a target area of
1 CM2 amount to some ten microamperes. The electromagnet of the cyclotron
weighs 330 tons and has a pole-piece 1.5 m in diameter. With some im-
provements such as phase and frequency stabilization, the cyclotron can
now also be used as a pulsed fast-neutron source for a time-of-flight

spectrometer. By adjusting the diaphragm system it is now possible to
produce intense and highly monochromatic (energy spread 4:0.2%) ion beams.
One of the main fields of research in the cyclotron laboratory is that of
fast-neutron spectrometry. In (d,n) and (a,n) reactions at E d = 20 Mev
and E 4
a a 40 Mev respectively, neutrons can be obtp-ined with energies up
to 40 Mev. The first experiments in this field were in the production of
monochromatic neutro%s of up to 7 Mev by the reaction T(p,n)He3. Time-of-
flight spectrometry experiments were started ill 1954. The resolving time
of the recording apparatus musz be of the same order as the duration of a
neutron pulse, i. e., 42 mpec. In normal conditions the width of a
neutron pulse was not more 'than 10 mp ec. Investigation of the relation-
ship between pulse shape and cyclotron parameters showed that it was pos-
sible to produce doublet pulses without any effect of the pulse width
upon resolution. The characteristic resolving time of the spectrometer
was 2-5 mp sec. The first~single-channel modification of the spectrometer
was developed in 1956. Now,a multi-channel spectrometer is in operation,
which can be used directly as a high-speed slow-motion camera. It is
described in detail by B. V. Rybakov and V. A. Sidorov (of. Atomnaya

energiya, 5, no' 2 135 (1958)). As a final recorder, a 256-channel
analyzer of the MA-2 (ELA-2) type is used." The spectra of fast neutrons
from many nuclear reactions, especially of such which may be used for
production of monochromatic neutrons, have been investigated. The upper
energy limit in these experiments was, 15 Mev. The authors discuss special
experiments carried out with the use'of fast-neutron spectrometry. Some
~p:n~ and (d,n) reactions in D, T, and He are described in detail. In
d n reactions, the O'D neutron spectrv-in had a peak at Eri- Ed/2. A
detailed investig4tion of the continuous neutron spectra showed that the
shape of spectra is, in part determined b final-state pair interaction of
the particles produced. In D(d,n) and Hei(d,n) reactions, no final-state
pair interaction was found. Here the shape of spectra is determined by
the energy distribution of three particles. Other fast-neutron experimer1w
have been carried out to study the statistical properties of the nucleus.
A third group of such experiments covered the measurement of fission cross
sections. A special device has been constructed to study nuclear reac-
tions in which tritium is produced. (For details see 11. A. Vlasov,

TEXTi Thi2 is the continuation of previous papers (Ref8. 1, 2, 3) on the
(d,t) rea7,tion. A study of the latter makes it possible to determine the
degree of conservation of single-particle otates in -the inner, completely
filled sheils of nuclei. If these states are conserved, it is possible to
determine the neutron binding energy in th% sh?lls or the neutron tragsi-

Pig. I shows typical spectra for eaoh target. In addition to the tritons
resulting from (d,t) raaction,3 ~)f 0!8 and magnesium isotopes, a larUe
group of tritons waa produced by (d,t) reactions of 0 at E t = 10.5 Mev.
18 17
In the rea-,tion 0 (d")o . . four g-roups of tritons are observed, which
correspond to' the ground state and to the three excited states of 017
having energies of 0.871 3.06, and 5.3 Mev, Fig. 2 shows the angular
distribut ions of the four groups, which agree with the angular momenta
I = 2. 0, 1 and 1 of the neutron. There were intense transitions to the
ground state (I = 2) and to the first exe~ited state& = 0). The con-
~'igurationT (d 5/2)? and (s 1/2 )2 Jn the nucleus of 0 are strongly inter-
mixed, and there is only a slight admixture of the configuration (d 3/2 )2.
The probability ratio of the configurations (d 5/2)2 , (s 1/2)2, and(d 3/2) 2
in the groand state of 0 is is (d 5/2)2/(sl/2) 2 = 3.9 + 1.0 and
(d 5/2 )2/ (d 1-12 )2 > 10. In the case of 018. the weakest binding is that of

the d-neutron, while in the case of F 19 , it is that of the s-neutron.
The 3.06-Mev and 5.3-Mev levels are excited by ejection of a p-neutron.
It is noted that the 3.058-L'itev level has a negative parity and a I /2-spin.
The 3.06-Mev and 5.38-blev states are of the hole type. In this way, the
authors were able to calculate the values of neutron binding energy in the
018 and F19 nuclei for different states. The ground state of Lig 23
and a group of states are very likely to be excited in the reaction
Mg 24(d,t)t1g23 at an energy of about 2.5 Mev. The angular distribution
of the first group (Fig. 3) is in good agreement with I = 2. The angular
distribution of the second group may have different components correspond-
ing to 1 = 2, 1 = i9 etc. In the case of T,1g2A' the s- and d-shells are
18 19
probably much less intermixed than in the case of 0 and F . The group

tritons have been found in the reaction Mg2 (d,t)Mg25. These groups
correspond to the well-known jevels of the Mg 25 nucleus. The results
obtained for the reaction Mg2 (d,t)lAg25 can be explained by the shell
model if the neutron in Mg 26 is in the d-state, with a small admixture
of the s-state. The principal results of the present work are illustrated
in Table 3. The authors thank the co-workers of the cyclotron laboratory
for irradiations; V. S. Zolotarev and his co-workers for the preparation
of enriched Mg 25 -and Mg 26 isotopes; and V..M. Strutinskiy and A. 1. Baz'

Iradioactivity of HS is in error. An analysis of the binding energy
Iof nuclei with known masses indicates that there is likewise no

Several arguments are advanced to demonstrate
4 5. 4
Ithat H , H , and n as well as the heavier hydrogen and neutron iso-
Itopes lie beyond the limits of stability with respect to decay with
Inucleon emission. Nevertheless, it is concluded that the determina-
Ition of the energy of the virtual states in these and other unstable
Inuclei is of interest from the'point of view of determining the po-
sition of the stability limit and the isotopic spins of excited
!states of isobar states. The results can also cast light on the pos-
sible existence of neutron drops with density lower than nuclear.

ABSTRACT: This is a continuation of earl iier research with He3(ZhETF
.jv. 45, 1416, 1963) and is aimed at attaining polarized neutrons of
Ihigher energy than in the past. The energies of the incident deu-
terons ranged from 9 to 19 MeV and analysis was by means of scatter-
ing from a gaseous helium scintillator connected for a coincidence
circuit with two neutron counters. To exclude the effects of gdo-
metrical asymmetry, the neutron spin was turned through 900 in the

scattering direction from left to right and vice versa being pro-
duced by reversing the direction of the current in the solenoid.

The polarization of the neutrons in the reaction T(d, n)He at a
laboratory angle close to 300 exceeds 50% over a wide range of deu-
teron energies, so that strongly polarized neutrons with energy UP
to 40 MeV can be produced by this reaction. Resonance effects pre-
viously observed upon variation of the cross section of the reactions,'
4
T(d. n)He in the ground and 20-MeV excited states, as well as in
dT scattering, were also observed in the present results. These
resonance effects must be taken into account in the phase shift
analysis of the a:-n scattering, and are connected with the excited
states of the He5 nucleus (16.7 and 20 Mev). "The authors are
grateful to S. P. Kalinin and N. 1. Venikov for interest in the work
and for ensuring operation of ~he cyclotron, and also V. A. Kovtun

,SOURCE: Yadernaya fizika, v. 2, no. 2, 1965', 239-242
1TOPIC TAGS: neutron scattering, nuclear scattering, alpha particle, proton scat-
tering, neutron polarization, proton polarization
;ABSTRACT: The asymmetry of na-scattering for 45 to 1500 is measured for the case of
with enevgies of 25 1 1.25, 27.8 1 0.9 and 34 1 0.75 Hev. The neutrons
!were produced in the T (d, n) He4 reaction at an angle of 300 with deutron energies-
lof 9.1 t 1.3, 12.0 f 1.0 and 19.0 � 0.8 flev. The results are compared with the
angular relationship of polarization in pa-scattering, interpolated to the same
Aproton energies from the available data for other energies (21.9, 20.8 and 40 Mev).,
![Satisfactory agreement is found between the angular relationships of asymnietrj In
na- and pa-scattering, and both relationships show identical divergence from the
predictions of phase analysis extrapolated from the energy region below 20 Mev.
