Formation of the final charge state of particles sputtered by an ion beam from a solid surface in the case of resonant transitions
Bandos I. A., Slyusarenko Yu. V., Sobolev A. Yu., Kova A. G.
The probability for ionization of a sputtered ion as it moves away from the surface is analyzed in the case of resonant atom-solid transitions. In this case it is possible to derive explicit solutions for a realistic energy-density function of the electron states, rather than exclusively for a model function as in the case of nonresonant transitions. Expressions are given for the ionization probability in two model cases. The behavior of this probability as a function of the velocity of the escaping ion is different from that in the case of nonresonant transitions. © 1994 American Institute of Physics.
