Abstract
The hyperspherical harmonic expansion method implemented with suitable correlation factor is applied to solve the Schroedinger equation for systems with A = 3, 4 nucleons and A = 16 bosons interacting via central potentials. The merits of the correlation factor in fastening the convergence of the expansion are evident. The results obtained for threebody systems are completely satisfactory, but, for A > 3 some problems occur when the correlation factor contains only pair correlations and the expansion is limited to the elements of the potential basis.
