Stopping power calculation of 4He, 7Li, 12C, 16O ions in aluminum, copper, silver, gold, polypropylene and polycarbonate targets for the energy range 1-14 MeV/n

The Modified Bethe-Bloch formula depends on several corrective terms; the most important of these is undoubtedly the shell correction especially for energies of a few MeV/n, its contribution can exceed 10% of the stopping power. The charge state of the incident ions also influences in this latter, particularly for heavy ions at intermediate speeds 2Z1V0 >= V >= V0Z31. In the present work, we have proposed an expression for the stopping power's calculation of charged particles which is deduced from the Modified Bethe-Bloch formula, our expression is based principally on accurate experimental data of protons' stopping power, without having to determine the shell correction and the mean ionization potential of the absorber film. We have calculated the stopping power of 4He, 7Li, 12C, 16O ions in Aluminum[1,14]MeV/n, Copper[1,12]MeV/n, Silver[1,5]MeV/n, Gold[1,6]MeV/n, Polypropylene[1,3]MeV/n and Polycarbonate[1.2,2.9]MeV/n. Good agreement was found between our results and those given by experimental stopping power databases, Modified Bethe-Bloch formula, SRIM-2013, ASTAR and MSTAR calculation codes.
