Polarizational stopping power of heavy-ion diclusters in two-dimensional electron liquids

摘要

The in-plane polarizational stopping power of heavy-ion diclusters in atwo-dimensional strongly coupled electron liquid is studied. Analyticalexpressions for the stopping power of both fast and slow projectiles arederived. To go beyond the random-phase approximation we make use of the inversedielectric function obtained by means of the method of moments and some recentanalytical expressions for the static local-field correction factor.
