In this paper, excited states in 137Xe have been studied by using the near-barrier, single-neutron transfer reactions 13C(136Xe,12Cγ)137Xe and 9Be(136Xe,8Beγ)137Xe in inverse kinematics. Particle-γ and particle-γγ coincidence measurements have been performed with the Phoswich Wall and Digital Gammasphere detector arrays. Evidence is found for a 13/2+2 level (E = 3137 keV) and for additional, high-lying 3/2- and 5/2- states. The results are discussed in the framework of realistic shell-model calculations. These calculations are also extended to the 13/2+1 and 13/2+2 levels in the N = 83 isotonic chain. They indicate that there is a need for a value of the neutron 0i13/2 single-particle energy (ESPE = 2366 keV) lower than the one proposed in the literature. Finally, it is also demonstrated that the population patterns of the j = ℓ ± 1/2 single-particle states in 137Xe are different for the two targets used in these measurements and the implications of this effect are addressed.
