摘要: A new approach is presented to the calculation of charge density induced around a charged point particle in electron gas; this includes contributions beyond those considered linear-response theory. The method can be used treat impurities with infinite as well finite mass. Results from calculations various charges, positive and negative, are presented. In particular, results for distribution positron positron-annihilation rates obtained compared other authors experiments.
