Abstract
In recent years predictions on the off-shell behavior of composite particles interactions have been made by some theoretical models. The goal of this paper is to test them by using9Be nucleus. The bound state problem of9Be considered as aα—α—n three-cluster system is solved in configuration space. Several on-shell equivalent local and nonlocal forces for theα—α andn—α interactions are used for calculation of the low lying negative parity spectrum of9Be, and also of the charge density, quadrupole moment, and the correlation density of9Be ground state. The contributions to the calculated quantities of different partial waves of the two-body forces are examined and discussed.
