Energy loss of heavy ions in solids at energies below 5 MeV/u

摘要

A comparative study of various cnergy loss formulations has been made by comparing the calculated stopping power values with the corresponding experimental values for projectiles 6<=Z<=79 in the energy region approx 0.1-5.0 MeV/u. SOme systematic and interesting trends have been observed in case of LSS theory. The limitations of TRIM and SRIM calculations have been demonstrated. Stopping power calculations using Hubert et al formulation have been extended successfully beyond its recommended range of validity i.e. 2.5-500 MeV/u down to energies as low as 0.5 MeV/u for projectiles Z<=29 in targfets upto copper.
