Target Dependence of Post-Collision Effects in Ionization by Proton Impact
Journal of Physics B: Atomic, Molecular and Optical Physics
Abstract
We have measured and calculated double differential cross sections for ionization of Ne and Ar by 75 keV proton impact for a broad range of fixed projectile energy losses as a function of scattering angle. Along with data obtained previously for lighter targets this made possible a systematic analysis of post-collision effects between the scattered projectile and the continuum electron in the exit channel as a function of the target ionization potential. The data are consistent with an increasing strength of such effects with increasing ionization potential. However, second-order effects involving the projectile--residual target ion interaction also play an important role.
