INNER RADIATION EMITTED DURING BETA(+ -) DECAY AND RELATED PROBLEMS/

In the present study we consider the radiation emitted during beta(+/- ) decay and a few related problems of importance in applications. The so-called initial inner bremsstrahlung is emitted by the accelerated b eta(+/-) particle at very short distances from the maternal nucleus. T hen, the beta(+/-) particle moves with constant velocity through the e lectronic shells of the maternal atom (ion) and emits the inner bremss trahlung. Later the beta(+/-) particle leaves the maternal atom (ion) and begins to pass (with the same constant velocity) through the surro unding atoms and emits the usual bremsstrahlung. Likewise, both the ma ternal and surrounding atoms can be excited and even ionized either by the instantaneous change of the nuclear charge or by such a penetrati ng beta(+/-) particle. Then the excited atoms transit to the ground st ate emitting the so-called atomic transition radiation, which may be o bserved during or after beta(+/-) decay. Our present analysis includes the inner bremsstrahlung and inner atomic transition radiation, i.e., both continuous and discrete radiation from the maternal beta(+/-)-de caying atom (ion).
