“…together with results from recent experiments. Excitation energies and branching ratios are in agreement with recent data [3,4,12,131. For the 2 166, 2 565, 2 659, 2919, 2 939, 3 303, 3 642, 4 165, 4 721 and 5 172 keV levels the analysis of the decay is straightforward and does not give rise to any ambiguities.…”

The decay of low-lying levels in 55Co has been studied by means of the 54Fe(d,nγ)55Co reaction. Neutron energies were determined by time-of-flight techniques using a pulsed incident beam and a large liquid scintillator. Gamma rays in coincidence with neutrons were detected by a Ge(Li) spectrometer. Three levels at 4 720.8 ± 0.6 4 747.1 ± 0.6 and 5 172.4 ± 0.6 keV were strongly populated. The 4 721 and 5 172 keV levels have earlier been identified as the isobaric analogues of the 55Fe ground state and first excited state. On the basis of a comparison of the present results with previous particletransfer reaction studies it is suggested that the ground state analogue is split into the 4 721 and 4 747 keV levels. A study of excitation functions of 54Fe(d,n) transitions at incident deuteron energies between 5.0 and 6.0 MeV shows that the spectroscopic strengths obtained from (d,n) experiments in this mass region at these energies depend strongly on the incident energy.

“…[3] and [4]. This apparent discrepancy might be explained in terms of the decay of a level at 2 921 keV, reported to decay to the 2 166 keV level by a 755 keV transition [4,12,131. The energy value obtained (757.3 t 0 .…”

“…The 3724 keV Level. This is a well established level reported in several experiments [8,10,11] The 3942 and 4164 keV Levels. Spin and parity are either 1/2-or 3/2-for both levels [8,10].…”

“…The 805 keV transition to the 3942 keV level may be mixed with the 806.6 keV (3724 ~ 2918) transition and the 803.8 keV gamma ray in the 5SCo(//+) decay. The decay of the level has been verified by Lodin et al [13] and by Nelson et al [10]. Spin and parity for this level are difficult to measure because of the complicated feeding and decay, but J greater than 7/2 is unlikely.…”

The yield curve for the S4Fe(p, 7)~5Co reaction in the energy region Ev= 1.5-2.9 MeV has been recorded and the decay of ten resonances has been investigated. For six of the resonances the strengths have been determined. The angular distributions of the gamma rays have been recorded for four resonances to obtain spins or spin limitations for excited levels. In addition the lifetimes of 10 bound levels were determined with the Doppler Shift Attenuation Method. The isobaric analogues of the ground state and five excited states in 55Fe are discussed.
