and Be. The measurements were carried out using a modification of the setup and pro
.cedure employed earlier (A.P.Lukirshiy and Yc.P.Sav1n9v,0Rt.i spektr.,14,295,1963).,!
The materials for the most part were in the form of 1000 A thick coatings vacuum
evaporated onto glass plates; the halide layers were deposited over undercoatings
.of Al or Au an glass, mainly to provide the requisita conductivity for subsequent
absorption measurements. The results for R are presented in the formi of curves (R
!versus angle of incidence) and in' a table. The reflection curves were then used for.
calculating the index of refraction and the absorption coefficient by means of the "
usual Fresnel fomulas; the results are tabulated, To check the validity of the cal-~
~
culations and accuracy of the results, the absorption coefficients of some of the

are systematically higher than the values deduced from the reflection curves. A
Isimilar divergence was obtained for copper layers by L.G.Parratt (Phys.Rov.,95,359,
1954), who attributed it to decrease in density of the substance with approach to
the surface; this is also assumed to be the reavon for the divergences observed in
the present case. The results are discAwsed briefly In a final section. orig.art#

TITLE: 11 Emission bands of zirconium, niobium and molybdonuz and some chemical
compounds of these elements 0-loport, Seventh Conference on X-Ray Spectroscopy hold

TOPIC TAGS: x-ray spactrum, x-ray emission, zirconium, zirconium compound, niobium,

AgSTRACT: The M emission bands of Zr, Mb and Ho and their oxides were recorded in
continuation of earlier work on the M spectra of these metals (A.P.Lukirskiy and T.
11.Zimk1na,Izv.AN SSSR,Ser.fiz.27,330,1963). The spectrometer is described elsewhere
(A.P.Lukirskiy,lbid.25,215,1961); it has been equipped with a new gold-plated Grat-,
ing which makes it possible to record N, 0 and C lines. The oxide spectra were re-
corded only to assist in estimating the purity of the metal spectra. The U02C sPec-
trum was also obtained, as well as the spectrum of Mb containing 12.44% N. When the
anode was operated.cool (3 W, 12 to 20 mA an the X-ray tube) lines of C, 0 and N

were present and the M emission band of each metal had a double peak. When the an-
ode was operated sufficiently hot (45 to 100 =A, temperature greater tha 10000C) tba
C, 0 and X lines disappeared along with the double peaks. The double peak structure
was traced to carbon contamination, and the Mo2C spectrum was found to have this
double -peaked shape. The M emission bands of Kb and Mo showed the bends reported
in the--earlier paper of.this series (loc.cit.supra); that of Zr was simple. The sim-
pler-structure of the Zr band is ascribed to the smaller number of 4d electrons in
this metal. The band of puro zirconium (anode prepared from 99.99% zirconium iodide)
was recorded with a resolution of 0.2 eV and an anode temperature of about 10000C
(C, 0 and N contamination less than 0.1%). The only perceptible structure was a
weak line on the short wavelength side of the edge, similar to the lines reported
the previous paper for Nb and Mo. The width of the MV level was calculated from
_tbA_t..,0X_-the short wavelength edge, but the result vias lost In the corrections for
i_ns.tgumental broadening and temperature smearing of the Fermi surface, the final re-
sult be,Ing 0.04 � 0.05 eV. The width of the 5s-4d band was obtained from the width
of the M emission band, the long wavelength tail being eliminated by linear extra-
.polation. A value of 4.8 eV was found. The intensities of the linea of the M spec-
trum-wera :aoasured relatively to ~,C and-they are tabulated toll all throe metals. An

7he intensity ratios (intensities relative -to U.') of MrV V-Y:T lines of Mo, Kb and
Zr were, within the 20% experimental error, equal to the ra-.:.,js 5:4:2 of the n=-
bers of 4d electrons in the respective atoms. It Is concluded that the M emission
bands image the p and I states in the 4d bands, and characterize their widths and
shapes. Orig.art.has: 4 figures and 3 tables.

ABSTRACT: In order to study the fine structure of tbeabso iion edge, the authors
measured the coefficients of absorption, reflection, and the quantum yield of LiF in
the range 60 - 120 ev, which has not been thoroug121y iwestigated in the paot. The
measurements were rade with an x-ray spectrometer with diffraction grating using the
bremsstrahlung spectrum of a tungsten anode. The apparatus and procedures for its
use and for elimination of higher-order diffraction spectra were described elsewhere
(Opt. i spekbr. v. 19, 433, 1965 and earlier papers). The tested samples were thin
polycrystalline I&F films deposited!by vacuum evaporation on nitrocellulose substrates,
Sharp fluctuations of the absorptio4~ coefficient, which exactly duplicate fluctuations
in the spectral dependence of the qiiantum yield, were observed in the region of the
absorption K edge of the :Lithium ion 01r a seation extending from -60 to -60 ev. The

large valuen of the quantum yield (more than W%) 4nd its correlation with the abnorp-
tion coefficient indicate that the fundawntal role in the photowdoolon ntuir tho
absorption edge is played by Auger electrons. The sp!ctral dependence of t1a reflec-
tion coeMcient also displays a fine structure near the K edge, and agrees qualita-
tive3,y with the fine structure of the absorption spectrum. Howevero no exact corre-
lation is observed between the absorption and reflection coefficients, in view of the
complicated relation between them via the refractive Index, The authors thank A. M.
Rumsh for a discussion of the results and S. A. Gribovskly and No N. Ivanchik for

probably less pronounced because of inhibitory effects including those

TITLE: Magnetostatic, Field Due to a Crack-Type Defect
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy, Fizika,
ig6o, No.6,'Pp.,59-63
TEXT: An experimental study is reported of the effect of
crack-type defects in magnetized specimens on the magnetic
field outside the specimen. The specimen investigated was in
the form of a silicon iron plate containing 1.17% Si (120 mmlong,
80 mm wide and 45 mm thick). The defeat was imitated by a
rectangular gap (26 x I mm) at the :;entre of the specimen and
perpendicular to its- longitudinal axis. The, arrangement is;
illustrated in Fig.1, where 1 is the specimen, 2 the coils
and 3 the electromagnet pole piece*. The coils on the end of
the specimen were used to produce uniform magnetization over the
ent-ire specimen. The field above the defect was measured with
'the-aid of "ferroprobes" as described by Vlasov and Yershov
(Ref.4). In the present case, the ferroprobe method has the
following advantages over the usual ballistic; method'. In the
case of the ballistic method, the measuring coil must have a

26.4 mn respectively. The cui-ves marked a refer to the
average permeability-in the covering layer for d = 0, 7.5 and
26.4 mm respectively. It is concluded that the field due'to a
covered defect appears only for a certain definite value of the
magnetization of the specimen. . This is associated with the
.screening effect of the covering layer. The rate at which the
defect field increases with the average magnetization of the
specimen depends on the ratio of the magnetic reluctances of the
defect and the metal layers in its immediate neighbourhood.

Tl-:x'r: In an earlier paper Olef.12 Izveqtiya Vilzov SSSH,
Fizika, NO.3, 122, 196.1) it was shown that the field of a defect
of the type represented by a transverse crack can be determined
in the plane-parallel case in the range of medium nnd strong
fields by means of the formula
av
I + d/h
where H - field inside the defect assumed as being uniform,
d - thickness of the layer covering it, h - width of the defect.
The quantities d and h are determined by the dimensions of the

tion of If d according to Eq.(l) reduces to determining the field
inside the defect. This paper is devoted to solving this problem
aild to comj)aring theoretically calculated values of 11 wi th
exporimentaLly obtained values. A transcendental equaLort is
obtained and by eolving It according to the "regula falsi"

that, the magnitude of the field of a transverse crack-type defect.
can be calculated according to E(I.M. Experimental verification
of the results shows that the obtained results differ from

-ABSTRACT- The author has previously found that 11he efficiency of an alternating
,magnetic field gradually reduced to zero for demigne.Jzing magnetite specimens do-
'pends on the nngle between the initial magnetization and the demignetizing field.
The demagnetizing effect of an altornnting field of fixed initial strength is great-
~est when it is ydrallel to the initial magnetization, and least whon it is perpen-
,dicular thereto. The author refers to this phenomenon as the "unlaxial anisotropy of
!demagnetization." In order to determine whether demar;notizntion Is also onisotropic
'in pure ferromagnotic metals, the effect was Investigated In the case of 10 mm dia-

crystallites to measure 0.01 mm on the average, and x-ray studies showed them to be'
randomly oriented. The coercive force was 109 Oe.. Demagnetization intsotropy was
observed in thg cobalt discs. The ratio of the reduction of the magnetization pro-
duced by a small alternating demagnetizing field parnllel to the Initial magnetiza-
'tion, to the reduction produced by an eqtial demagnetizing field perpendicular there-
to, was about 1o6, when the initial magnetization was 100 gausses. This rntio %vns
smaller for greater initial magnetizations. The dependence of the demagnetizing cf-
ficiency on the angle between the demaGnetizing field and the initial nuignetization.
is calculated from the following assumptions, 1) each crystallite has a single axis
-of easy magnetization; 2) these axes are randomly oriented; 3) onch crystallite is
magnetized, if at all, in the direction of its easy axle; 4) the domagnetizing ef-
foct on a single crystallito of the alternating doinagnetizing field li proportional
to the component of the demagnetizing field in the direction of tho axis of the cry-
stallito. It is found that in order to obtain agreoment. with laxperimant for Inrgo
