Abstract : The γ -ray decay of an excited state in 131In, the one proton hole neighbor of the doubly magic 132Sn has been measured. A high-spin, core-excited isomer with T1/2 = 630(60) ns was identified following production by both relativistic fragmentation of a 136Xe beam and fission of a 238U beam. This state deexcites by a single γ -ray branch of 3782(2) keV from which direct evidence for the size of the N = 82 shell gap is inferred. The results are discussed in comparison to a shell-model calculation including configurations across the closed shells at N = 82 and Z = 50.
