“…Since 54 Co is a weak reaction channel, the raw 1α1p1n γ -ray spectra and matrices comprise significant contributions from the much more intense 1α2p1n reaction channel 53 Fe [26] and, less pronounced, from the 1α3p1n channel 52 Mn, from the 2α1p1n channel 50 Mn, as well as from 51 Mn (2α1p), 53 Mn (1α3p), 55 Fe (4p1n), and 56 Co (3p1n). The former three contaminations arise from events when one or more charged particles escaped the detection in Microball.…”

“…[51] the proton separation energy of 54 Co is S p = 4353.2 (16) keV, and the α-decay Q value amounts to Q α = 7807.6(9) keV. In addition, there is a low-lying, I π = 19/2 isomeric high-spin state known in the proton-daughter 53 Fe at 3040.4(3) keV excitation energy [52], and there is a low-lying, isospin T = 0, I π = 5 + state at 229(7) keV in 50 Mn [53]. Excited states and their γ -decay pattern are established for both nuclei as well [26,54].…”

High-spin states in the odd-odd N = Z nucleus 54 Co have been investigated by the fusion-evaporation reaction 28 Si(32 S,1α1p1n) 54 Co. Gamma-ray information gathered with the Ge detector array Gammasphere was correlated with evaporated particles detected in the charged particle detector system Microball and a 1π neutron detector array. A significantly extended excitation scheme of 54 Co is presented, which includes a candidate for the isospin T = 1, 6 + state of the 1f −2 7/2 multiplet. The results are compared to large-scale shell-model calculations in the fp shell. Effective interactions with and without isospin-breaking terms have been used to probe isospin symmetry and isospin mixing. A quest for deformed high-spin rotational cascades proved negative. This feature is discussed by means of cranking calculations.

New effective interaction forpf-shell nuclei and its implications for the stability of theN=Z=28closed core

The effective interaction GXPF1 for shell-model calculations in the full pf shell is tested in detail from various viewpoints such as binding energies, electro-magnetic moments and transitions, and excitation spectra. The semi-magic structure is successfully described for N or Z = 28 nuclei, 53 Mn, 54 Fe, 55 Co and 56,57,58,59 Ni, suggesting the existence of significant core-excitations in low-lying nonyrast states as well as in high-spin yrast states. The results of N = Z odd-odd nuclei, 54 Co and 58 Cu, also confirm the reliability of GXPF1 interaction in the isospin dependent properties. Studies of shape coexistence suggest an advantage of Monte Carlo Shell Model over conventional calculations in cases where full-space calculations still remain too large to be practical.

“…In addition, the Q EC value for the spin-gap isomer 53 Co m was measured relative to the 53 Fe ground state. 53 Co m decays dominantly to its isobaric analogue state (IAS) at 3040.4(3) keV in 53 Fe [78] for which a Q EC value of 8421.8 (12) keV is obtained. The Q EC value for 60 Zn was determined from the adjusted mass value for 60 Zn and the AME03 value for 60 Cu [29].…”
