Sammanfattning

High-spin nuclear isomers in N≈Z nuclei between doubly magic ⁴⁰Ca and ⁵⁶Ni provide an excellent testing ground for the nuclear shell model and questions related to isospin symmetry breaking in the vicinity of the proton drip line. The purpose of the present study is to investigate the possibility of weak electromagnetic decay branches along the decay paths of the 6526-keV 10⁺ isomer in ⁵⁴Fe. The isomer was strongly populated by means of the fusion-evaporation reaction ²⁴Mg(³⁶Ar,α2p)^54𝑚Fe. The Gammasphere array was used to detect γ-ray cascades emitted from the isomeric state. By means of γγγ coincidences, weak non-yrast decay branches can be discriminated, with the isomer’s half-life confirmed at T_1/2 =363(4) ns. The yrast 6⁺₁→2⁺₁ E4 cross-over transition was interrogated. The observations are compared with shell-model calculations.
