Number of particles in fission fragments
Abstract
In current simulations of fission, the number of protons and neutrons in a given fission fragment is almost always obtained by integrating the total density of particles in the sector of space that contains the fragment. Here, the semiclassical nature of this procedure and the antisymmetry of the manybody wave function of the whole nucleus systematically leads to noninteger numbers of particles in the fragment.
