Spectroscopic factors in dripline nuclei

Abstract

Single-nucleon knockout reaction studies of the proton-dripline nuclei ${}^9$C and ${}^{13}$O suggest an appreciable suppression of spectroscopic factors. In this work, we calculate the one-neutron and one-proton spectroscopic factors for the mirror pair ${}^9$C-${}^9$Li and ${}^{13}$O using two variants of the continuum shell model: the complex-energy Gamow Shell Model and the real-energy Shell Model Embedded in the Continuum. Our results indicate that the continuum effects strongly suppress the spectroscopic factors of well-bound orbits in the dripline systems, but have less impact on the spectroscopic factors of weakly-bound states.
