Global-Vector Representation of the Angular Motion of Few-Particle Systems

摘要

The angular motion of a few-body system is described by introducing angles that depend on the positions of the particles. The most adequate angles are determined variationally. The numerical examples presented for the td p molecule, Li atom, antiprotonic helium atom, triton and alpha particle convincingly show that this method is an excellent alternative of the partial-wave decomposition of the wave function.
