Mass Spectra Nuclear Fission Brian Williams

Mass Spectra Nuclear Fission Brian Williams Mass spectra. a most striking feature of the fission process, spontaneous or induced, is the fact that a parent nucleus decays into many daughter pairs. fission involves decay to neither symmetric nor asymmetric modes but decays to many modes and has a mass spectrum of the decay products. usually the decay yields are measured as a function of. The fission fragment yields for other fissile targets, in particular 233u and 239pu, are similar to those in figure 6.2, although the minima are not quite as deep and there are small displacements in a due to the differences in nuclear mass number. fast fission yields also have the same general character, for both fissile and fertile targets [8].

Nuclear fission of heavy (actinide) nuclei results predominantly in asymmetric mass splits 1. without quantum shell effects, which can give extra binding energy to their mass asymmetric shapes.
