TITLE: On positron annihilation in alkali-metal hydrides
SOURCE: Zh. eksper. i teor. fiz., v. 47, no. 2. 1964,* 659-666

ABSTRACT: In view of failures of earlier attempts to explain the
long-lived component of positron annihilation in ionic crystals,
the authors employed the self-consistent field method to develop a
new treatment of the time distribution of the annihilation radiation
in hydrides of alkali metals. It is shown that the presence of
two components in the lifetime spectrum of the positrons in the hy-
drides is due to the annihilation from different excited levels of
the system e+H-. The possibility of existence of a third component,

corresponding to annihilation from the ground state, is predicted.
The calculated curves of the angular correlation of gamma quanta in
the case of two-photon annihilation for the ground and first-excited
states of e+H- turn out to be quite close to those obtained by ex-
periment. This also offers evidence in favor of the proposed me-
chanism of annihilation. It is pointed out in conclusion tl~at the
proposea interpretation of the positron lifetime spectrum is appli-
cable not only to alkali metal hydrides but to other ionic crystals,
such as alkali-halide ones. The latter should include a third com-
ponent corresponding to annihilations from the ground state. "The
authors thank A. S. Kompaneyets for useful discussions and valuable
hints, and to A. N. Ivanova of the mathematical division, for de-
veloping a procedure for numerical integration of the equations,
as well as to A. I. Prikhozhenko of the same division for carrying
out the computation on the electronic computer. Orig. art. has:

amoiaits to a positronium oxidation.
The sub-barrier trcuisition of un electron
from a positronium atom to an acceptor may be more probable than the transition
from a hydrogen atom since in the case or a positronium the resonwice conditions
of the electron levels in the initial and final states should be letis inflexible
inasmuch as the positron, as a light and penetrating particle, can effectively j
absorb the recoil energy conxiected with -,,he difference in I;h,,! leve.1 positions. i

ABSTRACT: Tht! authors obtained the Mossbauer spectra of the Hi-VM series ef ferrites
and determined the values of t1v internal magnetic field on the TeS7 auclei with the
zinc concentration varied from 0 to 1 (at 300 and 78K). The appaxatud uiaed was of the
electrodynamic type, described in detail elsewhere (Zavodskaya 11iboratoriya No. 12,
1965). The ferrites were prepared by a standard ceramic technique. From the spectra
obtained it is deduced that with increasing zinc content, up to total substitution of
zinc for the iron ions, the ferrite goes over from the ferrimagnetic ordered state 'to
a paramagnetic state. The line splitting in the pure nickel ferrite can be attributed
to the existence of two fields with different ion positions. Smii.ller values of the
field correspond to tetrahedral positions of the iron ions. Both the 1>0sitive com-
ponents of the field and the electron density in the region increase slmaltaneous3,y.

ACC NR, AP6002704
At 78K the character of the Mossbauer spectra is similar to that at room temperature,,
except that the lines converge at larger zinc contents, the internal wguetic field
on the nuclei are larger, and the difference in the values of the interiml field due
to the different positions of the iron ions is also larger. With increasing zinc con-
tent, the field on the iron nuclei in both the tetrahedral and in the octahedral sub-
lattice decreases, in contradiction to the data obtained by Abe) 144swri, et al. ('T.

ABSTRACT: The purpose of the investigation was to determine the sigj) of the indirect-
ly induced (super-exchange) field at the nuclei of nonmagnetic 1,~in ')~~ iq introduced
Ion,
into an yttrium-iron-garnet matrix, previously observed by the authors (Pis'ma Z11ETF
v. 1, no. 1. 1965; PbYs. Lett. v. 15, no. 4, 1965). To this end the authors in-
vestigated the Mossbauer spectra of the same garnet sample placed in an external nag-
netic field. The change in the intesity ratios of the various spectral components,
due to application of the magnetic field, is attributed to the change in the char-
acter of the angular distribution of the components of the transitions � 1/2 (4/2)
-* � 1/2 (1/2). The distinctly observed increase in the splitting of -the Mosubauer
spectrum components indicates that the internal magnetic field at the tin nuclei co-

the tetrahedral Bublattice parallel and that of the octahedral sublattice antiparalle].
to the applied field. Since the internal magnetic field at the iron micleus is alwayE,
negative relative to the magnetic moment of its ion, it is concluded that -tile fields
of the nuclei, both tin and iron, situated in the some (octahedral) sublattice of thei
yttrium. iron garnet have the same sign. Several explanations of this fact will be I
discussed in a future article. The authors than S..Sherbinin for I
