MACHINE CALCULATIONS OF ENERGY TRANSFER PHENOMENA IN A BOMBARDED LATTICE

Abstract

A computer simulation investigates the ways in which an embedding lattice influences a collision event. Low energy events were studied with a Born-Mayer potential function; high energy with a Thomas-Fermi-Firsov potential. Conclusions were: (1) the lattice will increase ranges for particle energies above 400 ev; (2) the apparent mass concept is not a valid description of events in a lattice; (3) lattice effects will significantly modify the low energy portion of the target atom energy distribution function; (4) there is no evidence that a copper atom will rebound from a copper lattice.
