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 (SP). We have modeled this process as an inverse bremsstrahlung-type absorption of the SP quantum by an Ag[sup +] ion which undergoes a collision with the surface. We estimate the absorption probability and find it to be consistent with the Shea-Compton results.
