Espectro Retardado de Raios β em Fragmentos de Fissão do 235U

The time-dependent electron spectra of fission fragments from the thermal-neutron-induced fission of 〖235〗_U are calculated. The Gross Theory of nuclear beta decay is used to obtain the decay constant and individual electron spectra. The mean energy per fission carried by the electrons and number of electons per fission are also calculated. Comparison of these calculated spectra to experimental ones shows good agreement.
