Global-Vector Representation of the Angular Motion of Few-Particle Systems II
Abstract
The angular motion of a few-body system is described with global vectors which depend on the positions of the particles. The previous study using a single global vector is extended to make it possible to describe both natural and unnatural parity states. Numerical examples include three- and four-nucleon systems interacting via nucleon-nucleon potentials of AV8 type and a 3 system with a nonlocal potential. The results using the explicitly correlated Gaussian basis with the global vectors are shown to be in good agreement with those of other methods. A unique role of the unnatural parity component, caused by the tensor force, is clarified in the state of He. Two-particle correlation function is calculated in the coordinate and momentum spaces to show different characteristics of the interactions employed.
