The ν0h9/2 and ν0i13/2 strength at 137Xe, a single neutron outside the N=82 shell closure, has been determined using the 136Xe(α,3He)137Xe reaction carried out at 100 MeV. We confirm the recent observation of the second 13/2+ state and reassess previous data on the 9/2− states, obtaining spectroscopic factors. These new data provide additional constraints on predictions of the same single-neutron excitations at 133Sn.
