Improved Los Alamos model applied to the neutron induced fission of ~239Pu and ~240Pu and to the spontaneous fission of Pu isotopes

摘要

The Los Alamos model with multiple fission chances upgraded with (a) the linear relation between the average prompt gamma ray energy and the average prompt neutron multiplicity and (b) the dependence of the average fission fragment kinetic energy on the incident neutron energy, is used for the n+~239Pu and n+~240Pu reactions, and also for the spontaneous fission of ~237-241Pu isotopes.
