摘要：
Within the improved scission-point fission model, it is shown that the average neutron number per proton is not the same in fission fragments and is not equal to that in a fissioning nucleus. For the induced fission of U-238, Pu-240, Cm-244, and Cf-250, the dependencies of the fission-fragment neutron-excess ratio on the shell structure and excitation energy of fragment are studied.
