Abstract
Abstract A computer program, based on TRIM, has been developed to calculate the spatial density of nuclear energy deposited by incident ion beams as well as the magnitude of mixing caused by the ion. The program divides the collision cascade into spherical subcascades formed by energetic recoils and uses a modified Vineyard model of thermal spike mixing to calculate mixing magnitudes. Good agreement is found with experimental results of Fenn-Tye and Marwick [Nucl. Instr. and Meth. B18 (1987) 236] for the high energy mixing of Pt markers in Pd at 10 K. Mixing efficiencies for low energy ion bombardment are predicted from the model.
