Oneparticle properties of deformed N approximate to 28 oddN nuclei with weakly bound or resonant neutrons
(2009) In Physical Review C (Nuclear Physics) 79(1). Abstract
 Possible deformation of oddN nuclei with N approximate to 28 toward the neutron drip line is investigated using the Nilsson diagram based on deformed WoodsSaxon potentials. Both weaklybound and resonant oneparticle levels are properly obtained by directly solving the Schrodinger equation in mesh of space coordinate with the correct boundary condition. If we use the same diffuseness of the potential as that of betastable nuclei, the energy difference between the neutron 2p(3/2) and 1f(7/2) levels becomes very small or the N = 28 energy gap almost disappears, as the binding energies of those levels approach zero. This suggests that the ground states of those neutron drip line nuclei are likely to be deformed. In particular, the... (More)
 Possible deformation of oddN nuclei with N approximate to 28 toward the neutron drip line is investigated using the Nilsson diagram based on deformed WoodsSaxon potentials. Both weaklybound and resonant oneparticle levels are properly obtained by directly solving the Schrodinger equation in mesh of space coordinate with the correct boundary condition. If we use the same diffuseness of the potential as that of betastable nuclei, the energy difference between the neutron 2p(3/2) and 1f(7/2) levels becomes very small or the N = 28 energy gap almost disappears, as the binding energies of those levels approach zero. This suggests that the ground states of those neutron drip line nuclei are likely to be deformed. In particular, the spinparity and the magnetic moment of the ground state of oddN nuclei, S43(16)27 and S45(16)29, are examined. Moreover, it is suggested that in Mg39(12)27 lying outside the drip line the lowest resonant state may have 5/2(), if the N = 28 energy gap almost vanishes. (Less)
