“…These values are by 371(200) keV and 364(220) keV, respectively, lower than the extrapolated ones in the latest Atomic-Mass Evaluation (AME ′ 12) [6]. The isomer excitation energy equals to E x = 387(13) keV, which is very close to E x = 378 keV of the 2 + isomer in the mirror nucleus 52 Mn [38].…”

“…The absolute intensity of 42(10)% for the 2407-keV γ transition measured in 52 Co is much stronger than the 13.7(2)% 1352(10)-keV proton emission [26]. Hence, it is reasonable to assign the former as from the IAS in 52 Co with ME = −31426(10) keV, and the latter as from a 1 + state with ME = −31561(14) keV, which could be the analog 1 + state to the one identified in the mirror nucleus 52 Mn [38,39].…”

Mass excesses of 52 Co and its (2 + ) isomer are measured to be −34361(8) keV and −33974(10) keV using isochronous mass spectrometry at CSRe. Referring to the β -delayed γ emissions of 52 Ni, we identified a new excited state in 52 Co and assigned it as the T = 2, J π = 0 + isobaric analog state (IAS) of 52 Ni. This state is 135(17) keV less bound than that suggested previously based on the β -delayed protons of 52 Ni. We find that the mass of this IAS together with those of the IAS ′ s in 52 Fe, 52 Mn, and 52 Cr fit well into the Isobaric Multiplet Mass Equation.An interesting finding from this measurement is that the IAS in 52 Co decays dominantly via γ transitions while proton emission is almost negligible. This phenomenon could be due to very low isospin mixing according to the large-scale shell model calculations.

“…[12], as well as the data analysis procedures employed. (10) [12], we have assumed for the last level an energy of 378(50) keV from the value in the mirror nucleus 52 Mn, 377.749(5) keV [10,16], fixing in this way the excitation energies for the 52 Co levels. The error of 50 keV on the 378 keV level energy, which accounts for possible mirror energy differences (MED), was estimated in Ref.…”

Observation of the 2+ isomer in Co52

We report the first observation of the 2 + isomer in 52 Co, produced in the β decay of the 0 + , 52 Ni ground state. We have observed three γ-rays at 849, 1910, and 5185 keV characterizing the β deexcitation of the isomer. We have measured a half-life of 102(6) ms for the isomeric state. The Fermi and Gamow-Teller transition strengths for the β decay of 52m Co to 52 Fe have been determined. We also add new information on the β decay of the 6 + , 52 Co ground state, for which we have measured a half-life of 112(3) ms.

“…The n-p effective interaction in the deuteron [15] as well as d-n effective interaction in the triton [16] are assumed to have a Gaussian shape, while the Woods-Saxon shape [17] has been considered for the d-d effective interaction in the alpha particle. The transferred nucleon and deuteron bound states were generated in a Woods-Saxon real potential [5,6,7].…”

Abstract. An extended analysis of the nuclear reaction mechanisms involved within deuteron interaction with nuclei, namely the breakup, stripping, pick-up, pre-equilibrium emission, and evaporation from fully equilibrated compound nucleus, is presented in order to highlight the importance of the direct mechanisms still neglected in the analysis of deuteron-induced surrogate reactions. Particularly, the dominance of the breakup mechanism at low energies around the Coulomb barrier should be considered in the case of (d, x) surrogate reactions on actinide target nuclei.
