On the isotopic composition of fission fragments
We use a newly developed method, based on the original Brownian shape motion (BSM) model, to calculate fission-fragment isotopic yields Y(Z,N). Recent measurements of post-neutron isotopic distributions with better than 1 u resolution make it possible, for the first time, to test in detail this mode...
