3-BODY MODEL FOR LI-11 WITH SEPARABLE POTENTIALS

We report preliminary results of our calculations on the central gross features of the Li-11 nucleus considered as a three body, Li-9-n-n sy stem employing two-body separable potentials. Even with simple s-state binary interactions, the calculations to extract information on prope rties such as the binding energy, the momentum distribution of Li-9 an d of the halo neutron through the spectator functions as well as the r oot mean square separations of n-n and n-Li-9 pairs within the nucleus , give results which are encouraging enough to investigate the finer d etails of the system using more realistic two-body interactions.
