Cross sections for the production of neon recoil ions with projectile energies of 0.44 and 0.05 MeV/amu.

Abstract

The charge-state distribution of neon recoil ions produced by ion-atom collisions has been investigated with ${\mathrm{Ni}}^{\mathrm{p}+}$, ${\mathrm{Cu}}^{\mathrm{p}+}$, and ${\mathrm{N}}^{2+}$ projectiles. The dependence of recoil-ion production on the ionization state of the primary ions has been investigated for two projectile energies in an intermediate velocity range not previously studied. Absolute net-ionization and charge-specific cross sections have been determined and are compared with other experiments and with theoretical predictions.
