Abstract
Physical reasons are considered to explain the asymmetry of range dist ributions of implanted ions in amorphous solids. It is established tha t the appearance of negative asymmetry is due to the prevalence of ion electronic energy loss in the slowing down process. Nuclear stopping makes a positive contribution to the asymmetry value. A simple analyti cal expression for the asymmetry value is obtained. This allows extens ion of the possibilities of the well known program DIMUS to describe t he asymmetrical range distributions of energetic particles.
