results prove a great configuration correspondence between
the asymmetric catalyst (rather the asymmetric carrier) and
the spatial structure of the reacting molecule (Ref 13).
Special experiments proved that the protective colloid also
acts as asymmetric carrier (also Ref 2). The results
obtained finally prove that the metal particle is not in
the solvate cover of the micelle, but immediately contacts
the asymmetric molecule of the protective colloid. The course

TITLE: Anomalies of thermal expansion and scattering of X-rays for
small nickel particles near the Curie point
SOURCE: Fizika tverdogo tela, v. 6, no- 7, 1964, 2155-2159
TOPIC TAGS: x ray diffraction study, nickel, x ray scattering,

ABSTRACT: To ascertain whether crumbling of nickel leads to effects
other than loss of ferromagneLlsm, and to investigate the physical
properties of small ferromagnetic crystals, the author studied
by X-ray diffraction the thermal expansion of single-domain nickel
particles with average diameter -5 x 10-6 cm. The nickel powder
was prepared by an aerosol method, with metal vapor condensed in a
rarefied argon atmosphere. Most particles were oblate spheres and

had a narrow (2:1) range of particle size. Volume anomalies, ex-
ceeding by two orders of magnitude the corresponding effect in
bulk metal, were observed near the Curie point. The temperature
factor of X-ray scattering obeys in the main the predictions of
the Debye-Waller theory, exceptu" the temperature region near the Curie
point, where the heating of the particles is accompanied by a re-
duction in intensity and a smearing of the lines. After a repeated
heating of the particles, following annealing from temperatures
above the Curie point, these anomalies were eliminated. The ob-
served phenomena are explained under the assumption that the parti-
cles are made up of a large number of initially oriented magnetic-
dipole "subcrystallites," whic-h execute under the influence of the
thermal motion small rotational oscillations about the equilibrium
position. Orig. art. has: 3 figures.

metal vapor through a rarefied argon atmosphere (0.1 mm Hg) and con-
densation. Copper X-radiation was used,at Z 33 kV and 20 mA. A
lowering of the melting point was observed in the case of Bi and
Sb, and superheating in the case of the Pb particles. It id shown
that near the melting point the Bi and Sb lattices contract and
tend to a closer packing. Freshly prepared Bi powder contained an
amorphous fraction which had a long life at room temperature and
was stable against heating up to the particle melting point. The
results are explained by assuming minute single crystals to consist
of many subcrystallites, each with several face-centered cubic unit
cells on edge. This holds true even at room temperature. The na-
ture of the subcrystallite boundaries is still unclear. Unlike
mosaics, the subcrystallites are not affected by preceding heat
treatment. or origin. This hypothesis is confirmed by experimental
and theoretical results of other authors. "The author is grateful

Investigation of the Dispersion Degree of Aluminum Aerosols in
Dependence of the Conditions of Their Formation
Doklady Akademii nauk SSSR, 1959, Vol 127, Nr 2, PP 366-368
(USSR)
ABSTRACTt Fine-disperse metals stand out because of their high adsorDtive
and chemical activity. Therefore, the importance was felt of
investigating the relationship existing between dispersion
degree and activity for particles smaller than 10-5cm. Owing
to the difficulty met in preparing particles of sufficiently
similar size in the mechanical way, the method by Gen, Zellmanov
and Shallnikov (Ref 1) was applied. Aluminum was evaporated on
a tungsten spiral in a glass flask filled with inert gas
(Ar, Fie, H). The loose precipitates forming on the cooled flask
wall exhibited a different coloring depending on pressure and
kind of gas. The black (finer) precipitates tended to self-
ignition in the air. The dispersion of the aerosols was
investigated by means of the EMZ electron microscope. The
degree of dispersion was determined by counting and measuring
Card 1/3 the particles on photographs (Fig 1). The differential and

integral distribution curves were in all cases similar to those
shown in figure 2 for an argon pressure of 27 mm. The dependence
of the weight average of the particle diameters on pressure and
kind of gas is illustrated in figure 3. In each gas a maximum
diameter characteristic of the respective gas is attained,
which does no more change with further pressure increase. In
the case of gas pressure below 1 mm the particle diameter was
smaller than the resolving power of the electron microscope
(,....10-7 cm). Table 1 specifies the oxidating properties and
the analysis of the aerosols oxidated in the air. Figure 4
shows the dependence of the metal content in the oxidation
product on the diameter of the particles. The oxide layer
thickness waB determined therefrom as amounting to about
10 molecular layers. The spherical form of the part4-cles is a

TITLE% A New Method of Evaporation (Vacuum Deposition) of
Aluminium from a Tungsten Wire
PERIODICALt Pribory i tekhnika eksperimehta, 1961, No.2,pp.196-197
TEXTt A new method is described of evaporating aluminium, a
method of sliding the drop along the vertical. The instrument
consists of a 12 cm long evaporator a which is twined from four
0.5 mm dia. W wires and fixed vacuum tight on current supply leadeg
which are cooled by running water and arE insulated from the body.
A bent nickel-plated copper tube 6 is introduced through the lid,
using a rubber seal; this tube can be moved vertically and rotated
about its axis by means of the handle A , With the help of gearing
2. inside the tube, aluminium wire of 1.5 mm diameter is fed through
the rubber seal e. The tube is adjusted to the desired height
and is turned to the side away from the hot evaporator, which
allows the passage of about 50 to 60 A. Then, a second of 2 to
3 cm of aluminium wire is pushed out, which is fed into the
.,raporator by turning the tube. A bit of aluminium fuses rapidly

and contracts into a droplet. It wets the tungsten and slides
downwards, evaporating almost instantaneously without reaching the
bottom of the evaporator. By displacing the tube along the height
of the tungsten rope, the service life can be considerably increasod
thus reducing the tungsten consumption to about I g/1 g of
evaporated aluminium. If the aluminium wire is well insulated from
the current leads, the wire will not scatter during fusion. Other
wise a shunting of the evaporator may occur which leads to throwing
off sections of the wire and intensive scattering of fine droplets.
The described method has the additional advantage of axial
symmetry; no laborious oneration is necessary for producing the
tungsten spirals. The-tungsten wire rope can be easily twinad
by a hand brace. If necessary, the central tube feeding the
aluminium wires can be surrounded by several evaporators which operate
alternately. Acknowledgments are expressed to Yu.1. Fedorov
for his assistance in the practical work. There are I figure and

ABSTRACT: By means of a proportional counting tube it is possible, ahen
measuring neutron doses, to eliminate the 4' -sub-grc-und
(arioording to Hurst). The most essential disadvantaEe of this
method is caused by the uncontrolable ionization losses below
the threshold value). These are measured accurately for the case
that the recoil protons penetrate from a thick radiator into a
small gaseous slit which always takes place on the occasion of
the impinging of neutrons onto the surface of the radiator. It is
shown that, if the threshold value is 0,1 KeV, the thickness of
the ga-secus slit is I am and the ener&-y of the neutrcns to be rc-
corded wnounts to 3 MeV, the ionization losses amount to 31,-,
whilst Hurst estimates them only at -,, CO-1 . There are 3 tablc:i.

ABSTRACT: The design orbit in accelerators with straight line
sections is usuallv in the form of a closed curve
consisting of four straight line sections connerted by
four circular arcs of radLUS To and subtending an
angle of 90' at the centre one of the necessary
conditions for the actual orbit to coincide with the
design orbit is that the magnetic field should be zero
over the straight line sections and uniform over the
other sections, However. owing to leakage, the true
magnetic field always differs from the design field so
that it is always necessary to introduce the concept of

Eq (1), The actual distribution of the field is
normally of the form indicated by Fig 1, The effective
angles of sectors will decrease at low fields owing to
eddy currents and residual induction. Thev will also
decrease at high fields owing to saturation effects.
This will lead to the appearance of a well-defined
fourth harmonic of the distortion of the design orbit.
and to a reduction in the maximum energy of the
accelerated particles In the case of xnductive
acceleration the betatron ratio is also affected All
these effects have been investigated by the present
authors using a plane model The effects have been
found to be small towards the end of the acceleration
cycle, They have the biggest effect at the b(~glnning of
the cycle. In the latter case the amplitude of the
fourth harmonic of the design orbit becomes comparable
with the radial dimension of the working region and the
