We performed a measurement of the ⁵²Cr(d,p)⁢⁢ ⁵³Cr reaction at 16 MeV using the Florida State University Super-Enge Split-Pole Spectrograph (SE-SPS) and observed 26 states. While all of the states observed here had been seen in previous (d,p) experiments, we changed five L assignments from those reported previously and determined L values for nine states that had not had such assignments made previously. The g_9/2 neutron strength observed in ⁵³Cr in the present work and in the N = 29 isotones ⁴⁹Ca, ⁵¹Ti, and ⁵⁵Fe via (d,p) reactions is much smaller than the sum rule for this strength. Most of the observed L = 4 strength in these nuclei is located in states near 4 MeV excitation energy. The remaining g_9/2 strength may be located in the continuum or may be fragmented among many bound states. A covariant density-functional theory calculation provides support for the hypothesis that the g_9/2 neutron orbit is unbound in ⁵³Cr. The (α, ³He) reaction may provide a more sensitive probe for the missing g_9/2 neutron strength. Additionally, particle-γ coincidence experiments may help resolve some remaining questions in this nucleus.
