The 18Ne(d,t)17Ne and 18Ne(d,3He)17F single-nucleon pickup reactions were measured at 16.5 MeV/nucleon in inverse kinematics together with elastic and inelastic scattering channels. The full set of measured exclusive differential cross sections was compared with the mirror reaction channels on stable 18O after consistent reanalysis using coupled reaction channels calculations. Within this interpretation scheme, most of the spectroscopic factors extracted for the population of unbound states in 17F match within uncertainties with their mirror partners in 17O. However, for the deeply-bound neutron removal channel to 17Ne, a significant symmetry breaking with the mirror proton-removal channel leading to 17N is evidenced by an overall single-particle strength reduction.
