A new effective interaction for shell model calculations in the sdpf valence space
F. Nowacki, A. Poves
The neutron rich isotopes with Z<20, in particular those with neutron numbers around N=28,have been at the focus of a lot experimental and theoretical scrutiny during the last few…
The influence of pairing on the nuclear matrix elements of the neutrinoless double beta decays
E. Caurier, J. Menendez, F. Nowacki +1
We study in this letter the behavior of the neutrinoless double beta decay nuclear matrix elements (NME's) in the framework of the Interacting Shell Model. We analize them in terms…
Nuclear Structure Aspects of the Neutrinoless Double Beta Decay
E. Caurier, F. Nowacki, A. Poves
In this article, we analyze some nuclear structure aspects of the neutrinoless double beta decay nuclear matrix elements (NME), in the framework of the Interacting Shell Model. We…
Collapse of the N=28 shell closure in Si
B. Bastin, S. Grévy, D. Sohler +34
The energies of the excited states in very neutron-rich Si and P have been measured using in-beam -ray spectroscopy from the fragmentation of secondary beams of…
Coexistence of spherical states with deformed and superdeformed bands in doubly magic 40-Ca; A shell model challenge
E. Caurier, J. Menendez, F. Nowacki +1
Large scale shell model calculations, with dimensions reaching 10**9, are carried out to describe the recently observed deformed (ND) and superdeformed (SD) bands based on the firs…
