| Abstract: | We propose an approach to investigate the possible internal motions of three-body quantum-mechanical systems held together by pairwise potentials. The method utilizes the  shape-density functions which we define and then extract from the eigenwave functions of the system. Through these densities we determine the dominant geometric configurations and modes of internal motion of the 0+, 2+ and 4+ states of a model three-boson system with and without a repulsive core in the interaction.Research supported in part by NSF Grant No. PHY83-06584 and by The Science Fund of the Chinese Academy of Sciences |
