Closed-shell properties of O with {\em ab initio} coupled-cluster theory
Ø. Jensen, G. Hagen, M. Hjorth-Jensen +1
We present an \emph{ab initio} calculation of spectroscopic factors for neutron and proton removal from O using the coupled-cluster method and a state-of-the-art chiral nucl…
Computation of spectroscopic factors with the coupled-cluster method
Ø. Jensen, G. Hagen, T. Papenbrock +2
We present a calculation of spectroscopic factors within coupled-cluster theory. Our derivation of algebraic equations for the one-body overlap functions are based on coupled-clust…
Study of Resonant Structures in a Deformed Mean-Field by the Contour Deformation Method in Momentum Space
G. Hagen, J. S. Vaagen
Solution of the momentum space Schrödinger equation in the case of deformed fields is being addressed. In particular it is shown that a complete set of single particle states which…
Effective Interaction Techniques for the Gamow Shell Model
G. Hagen, M. Hjorth-Jensen, J. S. Vaagen
We apply a contour deformation technique in momentum space to the newly developed Gamow shell model, and study the drip-line nuclei 5He, 6He and 7He. A major problem in Gamow shell…
Generalized contour deformation method in momentum space: two-body spectral structures and scattering amplitudes
G. Hagen, M. Hjorth-Jensen, J. S. Vaagen
A generalized contour deformation method (GCDM) which combines complex rotation and translation in momentum space, is discussed. GCDM gives accurate results for bound, virtual (ant…
