The shell structure of magic nuclei far from stability is discussed in terms of the self-consistent spherical Hartree-Fock-Bogoliubov theory. In particular, the sensitivity of the shell-gap sizes and the two-neutron separation energies to the choice of particle-hole and particle-particle components of the effective interaction is investigated.

The second unique forbidden electron capture (EC) decay in 123 Te is calculated in the Proton-Neutron Quasi-Particle Random Phase Approximation (pn-QRPA), making use of Skyrme-type residual interactions. As in the allowed Gamow-Teller channel, the forbidden nuclear matrix elements depend sensitively on the competition between particle-hole and particle-particle correlations. Theory provides a l...

The correct use of energy-dependent single-particle level (s.p.l.) densities within particle-hole state densities based on the equidistant spacing model (ESM) is analysed. First, an analytical expression is obtained following the convolution of energy-dependent excited-particle and hole densities. Next, a comparison is made with results of the ESM formula using average s.p.l. densities for the ...
