Experimental work by Shea and Compton suggests that Ag{sup +} ions emitted from a roughened Ag surface irradiated by a nanosecond or picosecond laser beam may absorb the full energy of the Ag surface plasmon. We have modeled this process under the assumption that it proceeds through an inverse bremsstrahlung-type absorption of the SP quantum by Ag{sup +} ion which also undergoes a small-impact parameter collision with another ion or atom in the vicinity of the surface. We give a quantitative estimate of the absorption probability and find reasonable agreement with the Shea-Compton results. 8 refs., 2 figs.
