SCATTERING AND ENERGY LOSS FOR SLOW MOLECU-LAR IONS IN ELECTRON GASES IN SOLIDS
低速分子离子在固体电子气中的散射与能量损失

With the theory of electron-molecule scattering, we have investigated the scattering and energy loss for slow diatomic molecular ions in electron gases in solids and discussed the influence of the coherence effects between two ions to the energy loss. The scattering phase shifts are calculated using atomic IPM potential and the variable phase method. The stopping powers for atomic ions are compared with the results given by the nonlinear density-functional theory.
