Shell-model study of octupole collectivity near 208Pb
P. Van Isacker, M. Rejmund
We show that the collectivity of the particle-hole wave function of low-lying octupole 3^- states in doubly magic nuclei is mainly due to the neutron-proton interaction. Both the e…
Neutron--proton spin--spin correlations in the ground states of N=Z nuclei
P. Van Isacker, A. O. Macchiavelli
We present expressions for the matrix elements of the spin--spin operator in a variety of coupling schemes. These results are then applied to ca…
Partial dynamical symmetry and the vibrational structure of Cd isotopes
A. Leviatan, N. Gavrielov, J. E. Garcia-Ramos +1
The recently reported deviations of selected non-yrast states in Cd from the expected spherical-vibrator behaviour, is addressed by means of an Hamiltonian with U(5) partia…
Generic features of the neutron-proton interaction
Y. H. Kim, M. Rejmund, P. Van Isacker +1
We show that fully aligned neutron-proton pairs play a crucial role in the low-energy spectroscopy of nuclei. with valence nucleons in a high-j orbital. Their dominance is valid in…
Gamow-Teller transitions and neutron-proton-pair transfer reactions
P. Van Isacker, A. O. Macchiavelli
We propose a schematic model of nucleons moving in spin--orbit partner levels, $j=l\pm{\sfrac12}$, to explain Gamow--Teller and two-nucleon transfer data in nuclei above $^{4…
