Explanation for the 180° Rutherford backscattering anomaly in solids.

Abstract

An explanation is given for the unusual enhancement in the Rutherford backscattering yield at 180° found by Pronko and co-workers. It involves a nonstochastic dependence between inward and outward trajectories of backscattering projectiles. Results are presented of Monte Cario simulations in random solids which show excellent agreement with experiment without need of considering electronic disturbances induced by the projectiles.
