OPTICAL BREMSSTRAHLUNG ACCOMPANYING NUCLEAR BETA-DECAY

The production of light photons during beta decay in condensed media i s investigated. The internal and external bremsstrahlung processes are considered as mechanisms for the light emission. It has been found th at the total number of photons depends on the end-point of the beta sp ectrum and on the media characteristics. The degree of circular polari zation (CP) of the bremsstrahlung light photons emitted during beta de cay is analysed. It is suggested that cp of light bremsstrahlung may s erve as an additional source of information about the features of the weak interaction in nuclei.
