Dependence of electronic energy loss of light ions on the angle of emergence

Abstract

The emergence angle dependence of electronic energy loss for energetic light ions transmitted through thin foils is discussed. The connection between this dependence and the impact parameter dependence of energy loss (differential stopping) is considered. Charge asymmetry effects in the differential stopping are examined and the possibility of studying the proton-antiproton transmission through thin foils is discussed. Several aspects of the stopping of light ions carrying their own electrons, including screening effects and charge exchange processes, are considered.
