Notes:
The thick-target yield of characteristic x-rays from a series of gold-silver binary alloys has been determined experimentally (relative to the yield from the pure elements) under proton bombardment, using proton energies of 1. 5, 2. 0 and 2. 5 MeV. The yield per unit concentration of gold or silver varies with alloy composition because of the progressively varying effects of proton stopping power (specific energy loss) and x-ray self-absorption in the target materials. Theoretical yields have been calculated using tabulated data for stopping power and x-ray absorption. When both of these effects are taken into account, agreement with experiment is satisfactory. These results can be made the basis of stopping power and self-absorption corrections in proton-induced x-ray emission analysis.
