Inner-shell ionization of Ne, ${\mathrm{N}}_2$, and S${\mathrm{F}}_6$ by ${\mathrm{H}}^{+}$ and ${\mathrm{He}}^{+}$ bombardment

Auger-electron spectroscopy has been used to study inner-shell ionization in Ne, ${\mathrm{N}}_2$, and S${\mathrm{F}}_6$ by 1-5-MeV ${\mathrm{H}}^{+}$ and ${\mathrm{He}}^{+}$ ions. Comparisons are made with corrected plane-wave. Born approximation (CPWBA) and binary-encounter approximation (BEA) calculations. Multiple ionization effects in ${\mathrm{N}}_2$ have been analyzed, and substantial differences in equal-velocity ${\mathrm{H}}^{+}$ and ${\mathrm{He}}^{+}$ bombardment are shown.
