Abstract

Polycrystalline Al and Zn samples were irradiated with 30 keV Ar+ ions at room temperature and the changes of their electron work functions, Φ were measured by the Kelvin method. Similarly to what was earlier experienced with stainless steel the changes of Φ as a function of displacement per atom (DPA) were seen to be of extremal character. This can be considered as a manifestation of competing formation and annealing of displacements. Comparing the Lang-Kohn theory of work function with the present experimental results the changes of the Wigner-Seitz radii were evaluated. A differential law for the dependence of the Wigner-Seitz radius on DPA is proposed.
