Even-odd effects in prompt emission in fission induced by the charge polarization

摘要

The even-odd effects in prompt emission induced by the charge polarizationare investigated. The charge polarization influences the range of fission fragments forwhich the prompt emission quantities are calculated in the frame of the Point-by-Pointmodel. The way of considering the charge polarization: Z as a function of thefragment mass A or a constant Z value of |0.5| for all fragments affects the fissionfragment charge distribution Y(Z). Recent papers focused on proton and neutron even- odd effects in prompt emission showed that the even-odd staggering exhibited bydifferent prompt emission quantities are due to the Z even-odd effect in Y(Z) andZ(A) and to the N even-odd effect in the average neutron separation energy fromfragments. Prompt emission results for even-even and even-odd fissioning nuclei,obtained using different charge polarizations, are given.
