Weak-interaction and nuclear-structure aspects of double beta decay are reviewed. Starting
from effective electroweak lagrangians, decay rates for the two-neutrino and neutrinoless …

This review treats several pairing-related phenomena in nuclear systems, ranging from
superfluidity in neutron stars to the gradual breaking of pairs in finite nuclei. It focuses on the …

The development, present status and future perspectives of the Monte Carlo shell model are
discussed. The development and limitation of the conventional shell model calculations are …

The role of neutron–proton pairing correlations on the structure of nuclei along the N= Z line
is reviewed. Particular emphasis is placed on the competition between isovector (T= 1) and …

In the present study we generalize the self-consistent Hartree-Fock-Bogoliubov (HFB) theory
formulated in the coordinate space to the case which incorporates an arbitrary mixing …

Shell structure and magic numbers in atomic nuclei were generally explained by pioneering
work that introduced a strong spin–orbit interaction to the nuclear shell model potential …

The closed shell structure at N= Z= 28 is studied by a large-scale shell model calculation by
the quantum Monte Carlo diagonalization method. Latest crucial improvements of the …

The ground states of even-even Z= N nuclei are determined with the isospin generalized
BCS equations and the HFB equation. The calculations permit the simultaneous existence of …

We examine isovector and isoscalar neutron-proton correlations in an exactly solvable
model based on the algebra SO (8). We look particularly closely at Gamow-Teller strength …

The influence of the isoscalar and isovector L= 0 pairing components of the effective
nucleon-nucleon interaction is evaluated for several isobaric chains, in the framework of full …
