Energy loss of light ions in different carbon compounds

Abstract

Experimental data on the energy loss of light H, Li, B, and N ions in methane and H and N ions in benzene vapor have been presented for the range of ion energies from 0.01 to 0.6 MeV/nucleon. It has been shown that the energy loss in the compounds does not follow the addition rule for small ion energies, which indicates the necessity of taking into account the chemical bonds of the molecular targets. The deviation from the addition rule has been experimentally found to increase with the nuclear charge of the projectile ion.
