Vi. Vysotskii et al., THE PROBLEM OF GAMMA-LASER AND CONTROLLING OF MOSSBAUER NUCLEI DECAY (THEORY AND PRACTICE), Hyperfine interactions, 107(1-4), 1997, pp. 277-281
This paper discusses the control process of the radioactive Mossbauer
nuclei spontaneous decay probability. The possibility of using this ef
fect in order to produce an optimized gamma-laser is considered. For t
he first time, the experiment has shown radioactive lifetime doubling
for Fe-57 nuclei and a general lifetime increase (including conversion
and non-Mossbauer decay channels) by 2%.
