Beiiavior of Slow Electrons in Gases

L-changing Collisions in Cold Rydberg Gases

Using spectroscopic methods and time-resolved electron counting, it is found that clouds of cold Rydberg atoms can emit electrons over a surprisingly long time scale. Our observations are explained by l-mixing collisions between Rydberg atoms and slow electrons. The thereby created high-angular-momentum Rydberg atoms thermally ionize slowly and with large probabilities. Calculations supporting ...

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...
