Abstract
The values of the atomic particle–solid potential were obtained for the first time from experimental data on the energy spectra and angular dependences of backscattered particles. The proposed procedure for determining the potential has never been applied previously. It is shown that the obtained data do not depend on the potential approximation used. The ion–solid interaction potential differs markedly from the potential describing collisions in the gas phase. The screening constant increases by 10–15%. The increase in screening is due to an increase in the density of the electron gas in the region between the incident particle and scattering center.
期刊介绍:
Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
