ANALYSIS OF LI-9+N RESONANCES IN LI-10 BY COMPLEX SCALING METHOD - INTERACTION BETWEEN LI-9 AND NEUTRON

The ground resonance state with J(pi)=1+ and an excited resonance state with J(pi)=2+ in the Li-9+n system are investigated in the framework of the complex scaled orthogonality condition model. The resonance energies and widths are calculated for the folding-type central and l.s potentials between Li-9-core and neutron under a single channel approximation. In comparison with recent experimental data of the Li-10 system, the Li-9-n interaction is determined and the Li-9-core excitation effects are discussed. It is also stressed that determination of the Li-9-n potential obtained here is crucially important for the further quantitative study on the halo structure of Li-11.
