Sammanfattning

Proton-emission branches of the 10⁺ isomer in the T_z=−1 nucleus ⁵⁴Ni have been imaged with the active target and time projection chamber (ACTAR TPC) in an experiment conducted at the Grand Accélérateur National d'Ions Lourds (GANIL). The completed decay scheme allows derivation of the reduced transition strengths, B(E2;10⁺→8⁺) and B(E4;10⁺→6⁺), for the two competing γ-ray transitions. By means of a comparison with their well-known ‘mirror transitions’ in T_z=+1 ⁵⁴Fe, and aided by a variety of shell-model calculations in the fp model space, effective charges for E4 transitions near N=Z ⁵⁶Ni can be deduced: ε_π≈1.40 and ε_ν≈0.30. Mirror-energy differences are explored with various shell-model interactions and isospin-symmetry breaking terms.
