Abstract:

To study the properties of the symmetrical pseudoscalar meson theoretical potentials in nuclei, we apply them to Li6 that is expected to disclose the properties of two-body forces in nuclei as directly as possible and investigate how favourable these potentials are to the static properties of Li6. The potentials between two nucleons are divided into two regions at 0.6 times the meson Compton wave length. The outside potentials are derived from the symmetrical pseudoscalar meson theory, while the inside potentials are determined from nucleon-nucleon scattering experiments phenomenologically. The excitation energies of the levels and the nuclear moments are calculated according to the intermediate coupling method. The meson theoretical potentials are very favourable to Li6 without any modification, though the contribution from the potentials of the inside region is large. The order and spacing of the levels and spins are reproduced correctly up to the 3rd excited state. The corresponding spin-orbit coupling strength is large, namely, -8∼-12 Mev, and can also explain the nuclear moments in the same region, so it is rather close to the jj-coupling limit than the LS-coupling limit. The tensor force does not affect the results essentially.
