Abstract
The backscattering of K+ from an Ir(110) surface is used to determine the parameters of the screening function of the interaction potential. The energy range used (from 0.3 to 6 keV) corresponds to a potential range from 10 to 4000 eV. In the case studied the J. F. Ziegler, J. P. Biersack, U. Littmark [Stopping Powers and Ranges of Ions in Matter, edited by J. F. Ziegler (Pergamon, New York, 1985)] (ZBL) universal screening function gives a better fit to the experiment than the G. Molière [Z. Naturf. 2 a, 133 (1947)] screening function.Keywords
