Energy reflection from gold bombarded with keV protons at various angles of incidence

摘要

The calorimetric deuterium film method operating at liquidhyphen;helium temperature was used for measuring the energy reflection coefficient ggr; for 1ndash;10hyphen;keV protons incident on gold at angles of incidence up to 75deg;. H+2and H+3ions were used to obtain the lowest velocities. The growth with angle increases with energy. There is fair agreement with the theoretical results of Robinson and of Oen and Robinson.
