WebApr 27, 2024 · In the environment of a hot plasma, as achieved in stellar explosions, capture and photodisintegration reactions proceeding on excited states in the nucleus can considerably contribute to the astrophysical reaction rate. Usually, such reaction rates including the excited-state contribution are obtained from theoretical calculations as the … WebNUCLEAR PHOTODISINTEGRATION 3 teron photodisintegration one may crudely think of the photoproduction of a pion from one nucleon followed by resonant 3/2, 3/2 scattering from that nucleon and absorption by the other. It is also important to consider (19) s-wave photopion production followed by 3/2, 3/2 scattering from the sec in december general motors produced 6600
