Projectile Dependence of KL^l Vacancy Production Cross Sections of Al by H and He Ion Bombardments

Abstract

Spectra of Al K_α X rays induced by H and He ion bombardments in the energy range of 0.2–0.4 MeV/amu have been measured with a Bragg spectrometer and Z₁ dependence of single K- plus multiple L-shell (KL^l) ionization has been investigated. The result shows that the L-shell ionization probability of Al by light ion bombardments follows the scaling law of direct Coulomb ionization considering the binding energy correction.
