Phenomenological Study of Three-Body Force Based on the Energy Levels of the Alpha-Particle
Abstract
The contributions of the three-body force to the energies of the alpha-particle are estimated both in the ground state and in the first three T = 0 negative parity (Jπ=0-,2-,1-) excited states. These contributions just correspond to the deviations of the theoretical values of the energies of the alpha-particle, which are obtained with the realistic two-body force only, from the experimental ones not only in the ground state but also in the excited states. From this fact, it is shown that the three-body force is indispensable to reproducing the energies of nuclei with realistic nuclear interactions and that the three-body force may be determined in a phenomenological way.
