Title: Low-spin structure of the N = 82 nucleus Cs 137

Excited states in 137Cs have been studied by using the near-barrier, single-proton transfer reaction 10B( 136Xe, 9Beγ) 137Cs in inverse kinematics and performing particle-γ and particle-γγ coincidence measurements. The low-spin level scheme of 137Cs has been augmented: (i) The expected set of single-proton, seniority ν = 1 states has been delineated in its entirety; (ii) Another member of the v = 3 proton 0g 7/2 multiplet, a low-lying 9/2 + level, has been identified and this set of states now approaches completion; (iii) A second 9/2 + and a candidate 13/2 + level have been observed. Furthermore, the results are discussed in the framework of shell-model calculations in the proton 2s1 d0 g0 h shell.
