We include coupling-to-continuum degrees of freedom by using a Hartree-Fock basis built from a Woods-Saxon single-particle basis. This basis treats bound and continuum states on an equal footing. We find a significant quenching of spectroscopic factors in the neutron-rich oxygen isotopes, pointing to enhanced many-body correlations induced by strong coupling to the scattering continuum above the neutron emission thresholds.", "revisions": [ { "version": "v1", "updated": "2011-04-08T11:40:55.000Z" } ], "analyses": { "subjects": [ "21.10.Jx", "21.60.De", "31.15.bw", "21.10.Gv" ], "keywords": [ "spectroscopic factors", "proton removal", "microscopic coupled-cluster calculations", "neutron emission thresholds", "closed-shell oxygen isotopes" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "year": 2011, "month": "Jul", "volume": 107, "number": 3, "pages": "032501" }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 895605, "adsabs": "2011PhRvL.107c2501J" } } }
