AbstractAbstract
[en] Solid solutions of transition elements in copper, nickel, cobalt, iron, and aluminum matrices were analyzed by observing secondary ion emissions under bombardment with 6.2-keV argon ions. Enhancement of the production of solute-element ions was observed. An ion emission model is proposed according to which the ion yield is governed by the probability that an atom leaves the metal in a preionized state. The energy distribution of the valence electrons of the solute atoms is the basis of the probability calculation
