WebThe binary collision approximation (BCA) has long been used in computer simulations of the interactions of energetic atoms with solid targets, as well as being the basis of most analytical theory in this area. While mainly a high-energy approximation, the BCA retains qualitative significance at low energies and, with proper formulation, gives ... Weband Binary Collision Approximation (BCA) simulations [3]. While semi-empirical equations for sputtering yields can be used for simple systems, simulations allow one to study a signiﬁ-cantly larger volume of the many-dimensional parameter space for ion-solid interactions. Simulations provide information, such as
