There is a considerable interest in understanding the dependence of one-nucleon removal cross sections on the asymmetry of the neutron S_n and proton S_p separation energies, following a large amount of experimental data and theoretical analyses in a framework of sudden and eikonal approximations of the reaction dynamics. These theoretical calculations involve both the single-particle cross section and the shell-model description of the projectile initial state and final states of the reaction residues. The configuration mixing in shell-model description of nuclear states depends on the proximity of one-nucleon decay threshold but does it depend sensitively on S_n -S_p ? To answer this question, we use the shell model embedded in the continuum to investigate the dependence of one-nucleon spectroscopic factors on the asymmetry of S_n and S_p for mirror nuclei ²⁴Si, ²⁴Ne and ²⁸S, ²⁸Mg and for a series of neon isotopes (20 ≤ A ≤ 28).
