A search for γ‐ray transitions in which contains only one neutron outside the core, was carried out at the Argonne Tandem‐Linac Accelerator System. nuclei were produced using the reaction. In‐beam γ rays were detected in the Gammasphere Ge‐detector array and were correlated with β‐delayed protons using the Recoil‐Decay Tagging method. A γ‐ray line at 172 keV was assigned to and was interpreted as the transition between the single‐neutron and states. The measured energy splitting is compared with predictions of various mean‐field potentials. It is also used to calculate multi‐neutron configurations in light Sn isotopes. Prospects of using β‐delayed protons for tagging other exotic nuclei in the region are discussed.
