摘要: A previously developed structure-sensitive statistical model, incorporating the nuclear structure and deformation effects, has been utilised to study prompt mass distributions in fision other related characteristics. The principle of detailed balance applied calculate yield probabilities. fusion barriers penetrabilities fragments were estimated from a plus Coulomb interaction potential. fragment yields then obtained as product three quantities: level densities conjugates at their most probable excitation energies, barrier isobaric charge yields. calculations are free any arbitrary parameters. Comparison with experimental data for226Ra(p, f) atE p =11.1MeV,232Th(n, n =1.0 MeV,235U(n, and239Pu(n, thermal neutron energies for spontaneous fission of252Cf shows fairly good agreement.
