Abstract
Empirical formulas have been developed for the backscattering of H, D and He ions normally incident on solid targets. The parameters considered are the number-backscattering coefficient R N, the energy-backscattering coefficient R E and the mean fractional energy r E of backscattered particles (ions and neutrals). The formulation utilizes the fact that the scaling law predicted earlier for R N and R E as a function of the Thomas-Fermi reduced energy ε is improved when these parameters are multiplied by S t/S e LSS. Here S t is the total stopping-power, in which expressions including the Z 2-oscillations are used for the electronic stopping-power, and S e LSS is the electronic stopping-power given by the LSS theory when the projectiles are much lighter than the target atoms. The formulas obtained are valid for 10-3\lesssimε\lesssim102.Keywords
