摘要: Abstract The Los Alamos model, with multiple fission chances, was upgraded to include the linear relation between average prompt gamma ray energy and neutron multiplicity. A global, model-free parameterization of this versus charge mass number fissioning nuclei is obtained. fragment kinetic dependence on incident also taken into account. Employing model for n+235U n+237Np reactions, spectra, multiplicity are obtained in very good agreement experimental data, proving a better predictive power.
