Abstract

Three previously unknown high-energy γ-ray transitions between 4.2 and 5.4 MeV were identified in the T_z=-1/2 nucleus ⁵¹Fe following the fusion-evaporation reaction ³²S(²⁸Si, 2α1n)⁵¹Fe. These transitions represent decays of core excited states. The y rays were detected in the Ge detector array Gammasphere combined with the neutron detector system Neutron Shell and the charged-particle array Microball. The three transitions are related to the mirror transitions in the T_z= + 1/2 nucleus ⁵¹Mn, and the resulting mirror-energy difference diagram is discussed with predictions from large-scale shell-model calculations.
