Ionization of the He, Ne, Ar, Kr, and Xe isoelectronic series by proton impact
In this paper we report ionization cross sections of positive Li +, Na+, K+, Rb+, neutral He, Ne, Ar, Kr, Xe, and negative F-, Cl-, Br-, I - ions by impact of protons with energies ranging from 25 to 1000 keV. Cross sections of singly charged ions are relevant to the calculation of electron yields i...
