An empirical formula of electronic Stopping Cross Section, Se, for low energy ions, such as Li+,Be+,B+,C+,N+,O+,F+ and Ne+, in solid materials is established according to the experimental electronic stopping power data in solid media. The formula can be used not only to describe the experimental Z1 and Z2-oscillation of electronic stopping power, but also to describe very satifactorily the Se varying with ion energy, E. The projected rang distribution moments up to third order for ten light ion species from H+ to Ne+ in different substrates, such as amorphous Al2O3,SiO2, 20/25/Nb stainless steel, LiNbO3 and UO2, are calculated by use of the electronic stopping cross section formula proposed by the present authors and the nuclear scattering function which agrees with the WHB atomic interaction potential. Our theoretical results are compared with the experimental results published recently, and our projected ranges, Rp agree with the experimental measurements more closely in the low energy end of the energy regime which we deal with in the present work.
