Quenching of spectroscopic factors for proton removal in oxygen isotopes. Jensen, Hagen, G., Hjorth-Jensen, M., Brown, B. A., & Gade, A. Physical Review Letters, 2011. doi abstract bibtex We present microscopic coupled-cluster calculations of the spectroscopic factors for proton removal from the closed-shell oxygen isotopes O14,16,22,24,28 with a chiral nucleon-nucleon interaction at next-to-next-to-next-to-leading order. 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. \textcopyright 2011 American Physical Society.
