“…Using the time-delayed γ γ (t) coincidences between two HPGe detectors we have confirmed the excitation energy and the half-life of the 396.8-keV 420(13)-ns isomer reported in [19]. Figure 10 shows the coincident HPGe spectrum gated by the 363.7-keV transition with two additional gates.…”

“…This intensity is equal to 100% in absolute units giving a renormalization factor of 0.539 (19), which converts relative intensity units into absolute intensities. The β-n branch is 7.9(12)% and the direct groundstate feeding is 8.8 %.…”

“…A 420(13)-ns isomer was identified at 396.8 keV, which feeds the 363.3(5)-keV level by a 33.5(5)-keV transition [18][19][20]. The 33.5-keV transition was assigned as E1 [21] although no evidence was provided.…”

β−decay of65Mn to65Fe

The low-energy structure of 65 Fe has been studied by means of γ and fast-timing spectroscopy at the ISOLDE facility, CERN. A level scheme of 65 Fe populated following the β − decay of 65 Mn was established for the first time. It includes 41 levels and 85 transitions. The excitation energy of the β-decaying isomer in 65 Fe has been precisely determined at 393.7(2) keV. The β-delayed neutron emission branch was measured as P n = 7.9(12)%, which cannot be reconciled with the previously reported value of 21.0(5)%. Four γ rays and four excited states in 64 Fe were identified as being populated following the β-n decay. Four lifetimes and five lifetime limits in the subnanosecond range have been measured using the advanced time-delayed βγ γ (t) method. The level scheme is compared with shell-model calculations. Tentative spin and parity assignments are proposed based on the observed transition rates, the calculations, and the systematics of the region.

“…The physics of the Zn isotopes in the vicinity of 68 Ni reveals a complex interplay between the stabilizing effects of the N = 40 subshell closure [46][47][48] and the collective features observed in the Ge isotopes. In order to get deeper insight into the structure of the Zn isotopes, we used several large scale shell model calculations.…”

The high-velocity transient-field (HVTF) technique was used to measure the g factor of the 2 + state of 72 Zn produced as a radioactive beam. The transient-field strength was probed at high velocity in ferromagnetic iron and gadolinium hosts using 76 Ge beams. The potential of the HVTF method is demonstrated and the difficulties that need to be overcome for a reliable use of the TF technique with high-Z, high-velocity radioactive beams are revealed. The polarization of K-shell vacancies at high velocity, which shows more than an order of magnitude difference between Z = 20 and Z = 30 is discussed. The g-factor measurement hints at the theoretically predicted transition in the structure of the Zn isotopes near N = 40.

“…Experimental data for heavy Cu isotopes are very limited. In addition to the experimental determination of the 5=2 − ground-state spin-parity [19], two low-lying microsecond isomeric states were observed in 75 Cu [20][21][22]. No information on excited states in the Cu isotopes beyond 75 Cu is available in the literature.…”

The level structure of the neutron-rich 77 Cu nucleus is investigated through β-delayed γ-ray spectroscopy at the Radioactive Isotope Beam Factory of the RIKEN Nishina Center. Ions of 77 Ni are produced by inflight fission, separated and identified in the BigRIPS fragment separator, and implanted in the WAS3ABi silicon detector array, surrounded by Ge cluster detectors of the EURICA array. A large number of excited states in 77 Cu are identified for the first time by correlating γ rays with the β decay of 77 Ni, and a level scheme is constructed by utilizing their coincidence relationships. The good agreement between large-scale Monte Carlo shell model calculations and experimental results allows for the evaluation of the singleparticle structure near 78 Ni and suggests a single-particle nature for both the 5=2 − 1 and 3=2 The evolution of the shell structure is one of the key motivations to study atomic nuclei with large neutron excess. The goal is to understand effects due to this excess of neutrons that are responsible for deviations from the conventional harmonic oscillator description with a strong attractive spin-orbit coupling, which characterizes the shell structure and properties of nuclei near the line of β stability. Such deviations are related to the monopole components of the effective nucleon-nucleon interaction and their strong effects on the single-particle energies (SPEs). The spindependent central component influences the energies of all single-particle orbitals, while the tensor interaction alters the spin-orbit splitting when specific orbits are filled by neutrons or protons [1][2][3][4][5][6][7][8].For the chain of Ni (Z ¼ 28) isotopes between N ¼ 40 and N ¼ 50, theoretical models predict significant changes in the proton SPEs as the ν1g 9=2 shell is filled by neutrons [3,4,[9][10][11][12]. Here, the tensor force responsible for SPE shifts
