Stopping and Straggling of Slow Atoms in Electron Gas

Stopping of Slow Projectiles in Electron Gas 1

New analytical formulas for the electronic stopping power and the energy loss straggling of low velocity extended charge projectiles in the degenerate electron gas are calculated within the dielectric function method. The stopping and straggling effective charges Zeff of a projectile were analysed. They are found to differ one from the other and to depend on the electron gas density rs, on the ...

Dicluster stopping in a degenerate electron gas

In this paper we report on our theoretical studies of various aspects of the correlated stopping power of two pointlike ions (a dicluster) moving in close but variable vicinity of each other in some metallic target materials, the latter being modeled by a degenerate electron gas with appropriate densities. Within the linear-response theory we have made a comprehensive investigation of correlate...

Resonant charging and stopping power of slow channelling atoms in a crystalline metal

Fast moving ions travel great distances along channels between low-index crystallographic planes, slowing through collisions with electrons, until finally they hit a host atom initiating a cascade of atomic displacements. Statistical penetration ranges of incident particles are reliably used in ion-implantation technologies, but a full, necessarily quantum-mechanical, description of the stoppin...
