TOPIC TAGS:. germanium, photoconductivity, impurity center, recombination radiation,

ABSTRACT: This is a continue:tion of earlier investigations of the photoconductivity~
of germanium at helium temperatures and at sufficiently large concentration.of shallow
impurities (jump photoconductivity) (FTT V. 6,,1203, :L964), where itwas shown that
the main recombination process under these conditions is inter-impurity recombin
tion., The present.~ investigation is'an attempt to confirm the presence of..inter-
impurity transitions in germanium by direct observation of the radiation connected
with.such transitions. The particular transitions considered were arsenic ga.1lium,'
arid antimony - gallium in germanium at 2K The arsenic and gallium impurities vere
pIroduced by irradiating the original germanium in a reactor. The',original.germanium,
contained v
arious amounts of antimony. The sample was excited with continuous vh-ite

,~ion with emissionlof

in germanium is confirmed by the present experiments both as.a,whole, and in its de-
tails which involve the none ilibrium distribution of impurities and the dependence
qui
of the recombination probability on the distances,between them. Orig. art-has: A*

TOPIC TAGS:. germanium, photoconductivity, impurity center, recombination radiation,

ABSTRACT: This is a continue:tion of earlier investigations of the photoconductivity~
of germanium at helium temperatures and at sufficiently large concentration.of shallow
impurities (jump photoconductivity) (FTT V. 6,,1203, :L964), where itwas shown that
the main recombination process under these conditions is inter-impurity recombin
tion., The present.~ investigation is'an attempt to confirm the presence of..inter-
impurity transitions in germanium by direct observation of the radiation connected
with.such transitions. The particular transitions considered were arsenic ga.1lium,'
arid antimony - gallium in germanium at 2K The arsenic and gallium impurities vere
pIroduced by irradiating the original germanium in a reactor. The',original.germanium,
contained v
arious amounts of antimony. The sample was excited with continuous vh-ite

,~ion with emissionlof

in germanium is confirmed by the present experiments both as.a,whole, and in its de-
tails which involve the none ilibrium distribution of impurities and the dependence
qui
of the recombination probability on the distances,between them. Orig. art-has: A*

ABSTRACT: This is a continuation of earlier..work (ZhETF v -, 50, 2735, 1966),, an.d.,con-Al-
-tains more detailed information on the fatigue produced during opticaldestruction
of transparent bodies in polymers (polymethylmethacrylate,and polystyrene).: the ex-
perimental procedure,was the.,same as' in the earlier investigation. To e radiation
was a neodymium laser operating in theordinary-pulse mode. Thettests co'n-
sist,ed.of determining the influence of energy on the.-number ofirradiations necessary;:~
for the first visible crack in the material to appear or the change in the dimension;

the two tests has shown -that the true threshold of optical strength is approximately
one-third as high as expected from an analysis of results of dama.ge produced by
single irradiation. An investigation was made of the nature of~the irreversible',
changes dueto the fatigue occurring at pulse~energies lower than,critical (necessaryi,
