Total electron yields and stopping power of protons colliding with NaCl-type insulator surfaces

In this paper we report electron yields and stopping power of protons colliding with surfaces of NaCl-type insulators formed with the alkali-metal ions Li+, Na+, K+, and Rb+ and the halides F-, Cl-, Br-, and I-. We also report fitted models for the static and dynamic polarization potentials of the e...

Sumario:In this paper we report electron yields and stopping power of protons colliding with surfaces of NaCl-type insulators formed with the alkali-metal ions Li+, Na+, K+, and Rb+ and the halides F-, Cl-, Br-, and I-. We also report fitted models for the static and dynamic polarization potentials of the eight ions of interest. The calculations are carried out within the shellwise local plasma approximation using the Levine-Louie response function, instead of the usual Lindhard one, to account for the ionization energy. © 2007 The American Physical Society.
