Backscattering coefficients of H, D, and He ions from solids

Experimental data on the number-backscattering coefficient R/sub N/, the energy-backscattering coefficient R/sub E/, and the mean fractional energy r/sub E/ of backscattered particles are tabulated for H, D, and He ions normally incident on elemental solids. References through 1981 are covered. The dependence of R/sub N/ and R/sub E/ on incident energy is shown graphically for energies from about 10 eV to 100 keV by plotting the experimental data and the empirical formulas of Tabata et al.. Graphs are provided for 36 elemental targets of atomic numbers from 5 to 92
