THERMAL-BEHAVIOR OF RADIATION-DAMAGE CASCADES VIA THE BINARY COLLISION APPROXIMATION - COMPARISON WITH MOLECULAR-DYNAMICS RESULTS

Based on the profile of the energy deposition obtained using the binary collision model, we follow the diffusion of energy by solving a simplified version of the heat equation. An estimation of the molten zone compares very well with the molecular dynamics prediction for the same event. We discuss the reasons for this agreement and the relevance of such simplified procedure in terms of present-day computer limitations to simulate high energy cascades using molecular dynamics. © 1990, Materials Research Society.
