摘要
Experimental results on inelastic losses by ions of energy 10(3)-10(4) eV transmitted through thin solid films are presented and discussed. The C, Cu, Ag, and Ni films (from 35 to 900 angstrom thick) have been bombarded by He+, Ne+ and Ar+ ions. The angular and temperature dependence of energy losses of transmitted ions have been studied. Experimentally obtained values of inelastic losses appear to agree with the Lindhard-Scharff-Schott (LSS) theory. A step-like increase in inelastic energy losses has been observed for He+ ions transmitted through the Ni films undergoing ferro- to paramagnetic phase transition.
