A STUDY OF THE IONIZATION OF AL, SI, S, SC, TI AND V BY AR IONS IN THE ENERGY-RANGE 1-5 MEV

Thick elemental targets of Al, Si, S, Sc, Ti and V and compound target s of P, S, Cl, K and Ca have been irradiated with singly and doubly ch arged Ar ions. K X-ray yields from target (13 less-than-or-equal-to Z2 less-than-or-equal-to 23) and projectile (Z1 = 18) atoms have been me asured 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 compar ed to theoretical predictions. The bombarding energy dependence of Kbe ta/Kalpha ratios is determined for the Ar ions and for the metallic ta rgets.
