Inelastic processes at collision of helium atom with multiply-charged ion

Single-electron ionization, single-electron excitations and bielectron excitations in self-ionization states of helium atom discrete spectrum are studied on the basis of simple approach according to which the excitation of complex atom at collision with fast multicharged ion results from abrupt transfer of momentum atomic electrons. Ratios of cross sections of binary ionization to single one are presented, as well. Comparison of the obtained represented, as well. Comparison of the obtained results with the experimental data is carried out
