Green functions and projection operators in the semiclassical approximation
Abstract
Closed forms of the Green functions and projection operators for quantum mechanical systems of two and three interacting particles are derived in the semi-classical approximation based on the Wigner transformation. An application to high energy potential scattering yields very accurate amplitudes at large angles.
