Abstract : We investigate the near-threshold behavior of one-nucleon spectroscopic factors in mirror nuclei using the Gamow Shell Model, which simultaneously takes into account many-body correlations and continuum effects. We demonstrate that for weakly bound or unbound systems the mirror symmetry breaking effects are appreciable, and they manifest in large differences of spectroscopic factors in a mirror pair.
