Abstract :
Molecular dynamics simulations are presented for the stopping of a charged ion in an electron gas. Full Coulomb collisional processes are included, and the resulting particle wake and energy deposition profiles are examined. The present study is extensible to multicomponent plasmas, for evaluating parameters like dE/dx, straggling, blooming, and energy splits.
