Abstract
By using a phenomenologically successful Woods-Saxon potential, I study the shape and shell structure of (A) neutron drip line nuclei with , (B) neutron-rich nuclei related to the process with , and (C) one-particle spectra in the potential provided by the nucleus as a representative of so-called “island of inversion” (IoI) nuclei. First, the shell structure that is unique in very weakly bound neutrons is systematically studied, and the approximate neutron number of odd- nuclei at which spherical (or deformed) halos can be found is pinned down. Second, the difference of the shell structure in -process nuclei from that in stable nuclei is examined. Third, the similarity and the difference between the shell structure of IoI nuclei and that of IoI nuclei are analyzed. As a result, it is concluded that in Fe and Cr isotopes the deformation called “ IoI” continuing up to is unlikely.
