A MONTE CARLO CALCULATION OF HIGH-ENERGY SPUTTERING
A machine calculation using an IBM-704 High-Speed Calculator was used to determine the sputtering produced by high-energy (-- 100-kev) deuterons incident on copper metal. The initial displacement interaction between incident and lattice particles was taken to be Coulomb, and subsequent lattice ion--lattice ion interaction potential to be hard sphere. The value of the sputtering ratio in this energy range was found to be in agreement with that predicted by a theory of Goldman and Simon Various suggestions are given to improve the machine calculations and to include a screened Coulomb initial interaction which would enable the code to be used for lower energy incident particles.
