Reflection of light ions from solid surfaces

Abstract

Abstract The reflection of 20-50 keV7 Be from gold and silver targets has been studied experimentally and theoretically. The experiments were carried out using a radiotracer technique. Theoretical values of the reflection coefficients were derived from calculated range profiles. The study is an extension of earlier work and as found previously, agreement between theory and experiment is obtained. Reflection coefficients were also calculated for 1H, 2H, 3H and 4He incident on Nb. These calculations should apply to other heavy targets also.
