Lecture 6 Scattering theory Partial Wave Analysis

The phase shift δδδδl measures the ‚distortion‘ of Rkl (r ) from the ‚free‘ solution jl(kr) due to the presence of the potential V(r ) Attractive (repulsive) potentials imply that δδδδl > 0 (δδδδl < 0) corresponding to the wave being “pulled in” (“pushed out”) by the scattering center resulting in a phase delay ... ................
