Wannier-type threshold theory of multiple ionization

摘要

Wannier-type threshold theory predicts power dependence, sigma similar to E-mu, for the cross section sigma of the break up of a quantum particle into several charged fragments (E is the excess energy above the fragmentation threshold). The threshold indices mu are calculated for the processes (electron impact ionization and photoionization) that lead to n = 6, 7 or 8 electrons receding from a charged core.
