- The even-Z odd-N neutron-halo nuclei, which are the lightest neutron-halo nuclei heavier than Mg37, are explored by studying the shell structure unique in weakly bound neutrons for spherical or deformed shapes. It is pointed out that due to the narrowed N=50 spherical energy gap and a few resulting close-lying neutron one-particle levels, 1g9/2, 3s1/2, and 2d5/2, for spherical shape, nuclei with some weakly bound neutrons filling in those levels may be deformed and have a good chance to show deformed s-wave halos. Promising candidates are Cr472471, Cr492473, Cr512475, and Fe512677 in the case that those nuclei lie inside the neutron drip line. An interesting possibility of the deformed p-wave or s-wave halos is suggested also for the nucleus Ar351853.

- Some developments of nuclear-structure physics uniquely related to Copenhagen School are sketched based on theoretical considerations versus experimental findings and one-particle versus collective aspects. Based on my personal overview I pick up the following topics; (1) Study of vibration in terms of particle-vibration coupling; (2) one-particle motion in deformed and rotating potentials, and yrast spectroscopy in high-spin physics; (3) triaxial shape in nuclei: wobbling motion and chiral bands; (4) nuclear structure of drip line nuclei: in particular, shellstructure (or magic numbers) change and spherical or deformed halo phenomena; (5) shell structure in oblate deformation.

Shell structure of one-particle resonances in deformed potentials

- The shell structure of low-lying neutron resonance levels in axially symmetric quadrupole-deformed potentials is discussed, which seems analogous to that of weakly bound neutrons. As numerical examples, nuclei slightly outside the neutron drip line, Mg271239 and C15621, are studied. For the lowest resonance I obtain Iπ=Ωπ=5/2- for Mg39 which is likely to be prolately deformed, while Iπ=Ωπ=1/2+ may be assigned to the nucleus C21 which may be oblately deformed. Consequently, C21 will not be observed as a recognizable resonance state, in agreement with the experimental information.
