Low-lying States of Four-Boson Systems with a Repulsive Core and an Attractive Tail in the Interaction

摘要

The Schrodinger equation of a four-boson model system is solved via a variational procedure. The pairwise interaction contains a repulsive core and an attractive tail. The features of the low-lying states are extracted via an analysis of the wave functions. The decisive effect of symmetry is demonstrated. A classification of states based on the inherent nodal structures of the internal Wave functions is proposed.
