Spectroscopic factors in dripline nuclei

Single-nucleon knockout reaction studies of the proton-dripline nuclei C-9 and O-13 suggest an appreciable suppression of spectroscopic factors. In this work, we calculate the one-neutron and one-proton spectroscopic factors for the mirror pair C-9-Li-9 and O-13 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.

Single-nucleon knockout reaction studies of proton-dripline nuclei C-9 and O-13 suggest suppression of spectroscopic factors, with continuum effects strongly affecting well-bound orbits in dripline systems but having less impact on weakly bound states.
