WebThe binary collision approximation was the first simulation model applied to ion bombardment of solids, in particular to the range [7.1]. Some years later Robinson and Oen [7.2] found channelling by computer simulation with a BCA program. Because of this success many programs have since been developed. In condensed-matter physics, the binary collision approximation (BCA) is a heuristic used to more efficiently simulate the penetration depth and defect production by energetic ions (with kinetic energies in the kilo-electronvolt (keV) range or higher) in solids. In the method, the ion is approximated to … See more In the BCA approach, a single collision between the incoming ion and a target atom (nucleus) is treated by solving the classical scattering integral between two colliding particles for the impact parameter of the incoming ion. … See more The BCA simulations give naturally the ion penetration depth, lateral spread and nuclear and electronic deposition energy distributions in … See more • Collision cascade • Molecular dynamics • COSIRES conference See more The BCA simulations can be further subdivided by type depending on whether they only follow the incoming ion, or also follow the recoils … See more • SRIM offers a graphical user interface and is likely the most used BCA code now. It can be used to simulate linear collision cascades in … See more • Media related to Binary collision approximation at Wikimedia Commons See more
