Collisional stopping considering the induced potential created by ions in a free-electron gas

Mostrar todas las versiones(2)

The wake potential induced by heavy ions in a free-electron gas is used as the interacting potential in the binary collisional formalism (BCF). Detailed results are presented for the stopping power, energy-loss distributions, mean free path, and electron angular distributions. The results were compa...
