SMMC studies of N=Z pf-shell nuclei with pairing-plus-quadrupole Hamiltonian
K. Langanke, P. Vogel, Dao-Chen Zheng
We perform Shell Model Monte Carlo calculations of selected N=Z pf-shell nuclei with a schematic hamiltonian containing isovector pairing and quadrupole-quadrupole interactions. Co…
Non-trivial aspects of the onset of nuclear collectivity: Static moments
L. Zamick, D. C. Zheng
We consider several topics concerning static magnetic dipole and electric quadrupole moments ( and ) as signatures of the onset of nuclear collectivity. Having previously not…
Change of shape in the yrast sequence in 50Cr
L. Zamick, M. Fayache, D. C. Zheng
In shell model calculations for the yrast even spin states of 50Cr, the static quadrupole moments of the low spin states 2+_1 and 4+_1 are negative but those of the high spin state…
Large-basis shell model studies of light nuclei with a multi-valued G-matrix effective interaction
D. C. Zheng, B. R. Barrett, J. P. Vary +2
Large-basis shell model studies of low-lying excitations in light nuclei from 4He to 7Li have been performed with a multi-valued G-matrix effective interaction, as recently suggest…
Auxiliary potential in no-core shell-model calculations
D. C. Zheng, B. R. Barrett, J. P. Vary +1
The Lee-Suzuki iteration method is used to include the folded diagrams in the calculation of the two-body effective interaction between two nucleons in a no-cor…
Self weakening of the tensor interaction in a nucleus
L. Zamick, D. C. Zheng, M. Fayache
We examine several ``landmarks'' for the effects of the tensor interaction on the properties of light nuclei. These were usually discussed in the context of small-space shell-model…
