Abstract

Measurements of the low-temperature mixing of several 5d-4d bilayers by 600 keV Xe ions have strongly supported the assumption of a thermal spike mechanism. Quite disturbingly, however, the Au-Ag mixing rate appeared to exceed theoretical predictions by about a factor of 3. A closer examination of this system shows the discrepancy to be caused by the formation of a strongly nonuniform Au surface structure during irradiation. An improved value for the mixing rate is in reasonable agreement with predictions.
