Abstract
Several weak-coupling approximations are compared to identify the stop ping of non-relativistic ions in a two-dimensional electron layer. The high-velocity (Bethe-like) stopping is intrinsically quantum-mechanic al, and inversely proportional to V. Low-velocity behaviour is much cl oser to that in three dimensions.
