Neutron-proton asymmetry dependence of spectroscopic factors in Ar isotopes
Jenny Lee, M. B. Tsang, D. Bazin +20
Spectroscopic factors have been extracted for proton rich 34Ar and neutron rich 46Ar using the (p,d) neutron transfer reaction. The experimental results show little reduction of th…
Ab-initio coupled-cluster effective interactions for the shell model: Application to neutron-rich oxygen and carbon isotopes
G. R. Jansen, J. Engel, G. Hagen +2
We derive and compute effective valence-space shell-model interactions from ab-initio coupled-cluster theory and apply them to open-shell and neutron-rich oxygen and carbon isotope…
Open -shell nuclei from first principles
G. R. Jansen, M. D. Schuster, A. Signoracci +2
We extend the ab initio coupled-cluster effective interaction (CCEI) method to deformed open-shell nuclei with protons and neutrons in the valence space, and compute binding energi…
Spectroscopy of 24Al and extraction of Gamow-Teller strengths with the 24Mg(3He,t) reaction at 420 MeV
R. G. T. Zegers, R. Meharchand, T. Adachi +20
The 24Mg(3He,t)24Al reaction has been studied at E(3He)=420 MeV. An energy resolution of 35 keV was achieved. Gamow-Teller strengths to discrete levels in 24Al are extracted by usi…
Symmetry broken and restored coupled-cluster theory. II. Global gauge symmetry and particle number
T. Duguet, A. Signoracci
We have recently extended many-body perturbation theory and coupled-cluster theory performed on top of a Slater determinant breaking rotational symmetry to allow for the restoratio…
