Abstract

The <superscript>137</superscript>I nucleus, populated in the spontaneous fission of <superscript>248</superscript>Cm has been studied by means of prompt γ-ray spectroscopy using the EUROGAM2 array. Medium-spin yrast excitations in <superscript>137</superscript>I were observed for the first time. The experimental level scheme is compared to the shell model calculation with modified Kuo-Herling interaction. The theoretical predictions differ significantly from the experimental results, indicating that the excitation pattern in <superscript>137</superscript>I deviates significantly from the shell model scheme.
