• 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^<LSS>_e. 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^<LSS>_eis 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>≲ε≲10^2.
