Binary collision approximation
WebThe MARLOWE program simulates atomic collisions in crystalline targets using the binary collision approximation. It follows out the consequences of launching an energetic atomic projectile, from either an external beam or an interior site, into a target. WebFeb 1, 2024 · Binary-collision approximation for plasma-material interactions. Computationally modeling plasma-material interactions is challenging. For effective coupling with a particle-in-cell, a reduced model of ion interactions with materials must be used, such as the widely popular binary collision approximation [39], [1]. In contrast to n-body …
