We review various theoretical models which have been used to study the properties of the ground state and excited states of nuclei close to and beyond the neutron and proton drip lines. The validity and limitations of these models are discussed with applications to recent experimental findings such as di-neutron correlations in Borromian nuclei, the soft dipole excitations, direct two-neutron and two-proton decays, and odd-even staggerings of reaction cross sections. The role of isoscalar spin-triplet pairing interaction is also pointed out in the low-lying energy spectra as well as the spin- and isospin-dependent decay rates for N = Z and N = Z + 2 nuclei with mass A < 60. A characteristic feature of the Coulomb energy displacement of the Borromian nucleus 11Li is discussed in connection to the energies of isobaric analogue states (IAS) of T = 5/2 multiples in the A = 11 systems.
H. Sagawa is a theoretical nuclear physicist. Bachelor of Science, 1969 (Waseda University, Japan). PhD in nuclear physics, 1975 (Tohoku Univesity, Japan). After his PhD, he stayed in Niels Bohr Institute, Institut de Physique Nucl´eaire at Orsay, and National Superconducting Cyclotron Laboratory at Michigan State University as visiting Researcher. He worked at University of Tokyo and University of Aizu 1985–2012 as a faculty member. He is currently Professor Emeritus, University of Aizu and Senior Visiting Researcher of RIKEN, Nishina Center. His major interest is nuclear structure problems in exotic nuclei.
K. Hagino is a theoretical nuclear physicist. He received the doctoral degree from Tohoku University, Japan, in 1998 and worked as a research associate at the Institute for Nuclear Theory, University of Washington, before joining Yukawa Institute for Theoretical Physics, Kyoto University as an assistant professor in 2000. Since 2004, he has been working at Tohoku Univesity as an associate professor. He has been working on heavy-ion reactions around the Coulomb barrier, structure and reactions of exotic nuclei, and collective excitations of hypernuclei.
