A study of the ionization of Al, Si, S, Sc, Ti and V by Ar ions in the energy range 1–5 MeV

Abstract

Thick elemental targets of Al, Si, S, Sc, Ti and V and compound targets of P, S, Cl, K and Ca have been irradiated with singly and doubly charged Ar ions. K X-ray yields from target (13 ≤ Z2 ≤ 23) and projectile (Z1 = 18) atoms have been measured at energies ranging from 1 to 5 MeV. The K X-ray energy shifts are examined for both elemental target and projectile atoms. From the measured yields, the K X-ray production cross sections are calculated both for target and projectile atoms. Furthermore, the vacancy sharing between the K levels of the collision partners is examined and compared to theoretical predictions. The bombarding energy dependence of KβKα ratios is determined for the Ar ions and for the metallic targets.
