Many-body interactions incorporated into a binary collision model of radiation damage in solids

In this contribution we consider the model of N-body interactions in a collision cascade that advances in isotropic continuum. The model developed includes as a special case the well-known binary collision models and takes into account formation of athermal vacancy clusters and thermal spikes. It permits to obtain the statistically averaged space distributions of defects and thermal spikes. Besides the model explains the yield of clusters during sputtering. The model can be incorporated into any Monte Carlo scheme of individual collisions to obtain depth distributions of vacancies, interstitial atoms, and vacancy clusters produced by energetic particles.
