Few-body approach to diffraction of small helium clusters by nanostructures

Abstract

We use few-body methods to investigate the diffraction of weakly bound systems by a transmission grating. For helium dimers, He${}_2$, we obtain explicit expressions for the transition amplitude in the elastic channel.
