Energy broadening resulting from electron stripping process of a low energy Au(sup -) beam

摘要

Energy loss spectra of Au(sup +) ions produced from Au(sup -) ions by electron stripping in He, Ar, Kr and Xe have been measured in the impact energy range of 24-44 keV. The energy broadening of the Au(sup +) beam increases as the beam energy increases, and the spectrum shows a narrower energy width for heavy target atoms. The dependence of the spectrum width upon the beam energy and that upon the target mass are well described by the calculation based on the unified potential and semi-classical internal energy transfer model of Firsov's.
