Inelastic Energy-Loss Structure in Nonviolent Heavy-Atom Collisions

Abstract

Inelastic energy-loss measurements for small-angle scattering in ${\mathrm{Ne}}^{+}\to \mathrm{Ne}$ and ${\mathrm{Ar}}^{+}\to \mathrm{Ar}$ collisions are reported. The resulting energy-loss spectra display a structure which may be explained in terms of curve crossing and preionization.
