Electronic stopping power of Ta for Z = 11–18 atoms at energies 0–0.8 [formula omitted

Abstract

The velocity dependence of the electronic stopping power of Ta has been studied for 23Na, 24Mg, 27Al, 29Si, 31P, 34S, 35Cl 38Ar ions in the energy region 0–0.8 MeV/nucleon. By application of Doppler shift attenuation measurements, computer simulations and experimental nuclear stopping power values, the electronic stopping power was deduced in the previously uninvestigated velocity region v/ v 0 = 0–5.8 ( v 0 = Bohr velocity) in the framework of an empirical model. This model was obtained to reproduce the electronic stopping power of Ta for the Z = 11–18 atoms to within an uncertainty of ± 7%.
