Total ionization and ionization fluctuations in helium
Abstract
The mean energy for ion production W, the Fano factor F and some other quantities inherent to electron ionization cascades in helium are computed with semi-empirical cross sections for excitation and ionization. W = 46 eV and F = 0.21 at electron energy of 2.5 keV.
