| Abstract: | Nonlinear density functional results for the stopping power and straggling of ions moving slowly (υ ⪡ υf) in an electron gas are presented. A self-energy formalism is used to estimate the charge state of a proton moving at intermediate velocities in an electron gas. The contribution of the surface to the energy loss of slow ions is also analyzed, within the specular reflection model. |
