Ionization and Charge Exchange Processes Induced by Collisions of Protons with Atoms of Superheavy Elements

Abstract

The cross sections for charge exchange and ionization induced by collisions of protons with the energies from 0.01 keV to 10 MeV with atoms of the superheavy elements Nh (Z = 113), Fl (Z = 114), Mc (Z = 115), Lv (Z = 116), Ts (Z = 117), and Og (Z = 118) have been calculated. These cross sections at the energies E ≈ 0.01−100 keV and E > 100 keV have been calculated in the adiabatic approximation and in the Born approximation with the cross section normalization, respectively. Since data on the cross sections for superheavy elements under consideration are absent, cross sections for Xe (Z = 54) and U (Z = 92) atoms have also been calculated and compared with the available experimental data and theoretical calculations. The distinctive properties of the charge exchange and ionization cross sections for atoms of superheavy elements have been revealed using the results of this work.
