“…Due to its small uncertainty, the ISOLTRAP mass excess is taken as the final value in the new AME. 63 Fe The mass excess of 63 Fe was measured in three TOFI experiments [44][45][46] with an average value of −55550(170) keV. The ISOLTRAP measurement gives a mass excess of −55636.6(5.7) keV, which is in a good agreement with the TOFI experiments.…”

“…Due to its high precision, ISOLTRAP carries 100% significance in the determination of the 62 Fe mass in the new AME. 63 Mn The mass of 63 Mn was previously measured in three different experiments with TOFI [44][45][46], giving an average mass excess value of −46350(260) keV. This value is 2σ away from our measured mass excess of −46886.9(3.7) keV.…”

“…A clear improvement of the experimental uncertainties, mainly due to improved statistics, can be distinguished between the first and the second experimental runs. As an example, the statistical uncertainty of the 63 Mn frequency ratio was 8.1 × 10 −8 in the first run while in the second run the 64 Mn statistical uncertainty was 4.4 × 10 −8 . Unfortunately, due to the drop in the production yield of 66 Mn associated with the total transport efficiency and the decay loss due to the short half-life (64 ms), the uncertainty of 66 Mn is the largest.…”

“…The Q β value was measured to be 8510(100) keV, which corresponds to a mass excess of −52890(100) keV. Later, this 3 + level was shown to be an excited isomeric state [63]. The first measurement of the presumed 0 + ground state's half-life of 51(6) s was achieved by Bosch et al [64].…”

Surveying theN=40island of inversion with new manganese masses

High-precision mass measurements of neutron-rich 57−66 Mn and 61−63 Fe isotopes are reported. The new mass surface shows no shell closure at N = 40. In contrast, there is an increase of the two-neutron separation energy at N = 38. This behavior is consistent with the onset of collectivity due to the occupation of intruder states from higher orbits, in analogy with the well known "island of inversion" around N = 20. Our results indicate that the neutron-rich Mn isotopes, starting from 63 Mn, are most likely within the new island of inversion. From the new mass surface, we evaluate the empirical proton-neutron interaction and the pairing gap, both playing a significant role in the structural changes in this region.

“…Based on allowed β decay to the 3/2 − ground state of 67 Cu (log f t ∼ 4.7), a tentative spin assignment of (1/2 − ) was made for the 67 Ni ground state [73]. This assignment is further supported in the quasielastic reaction work of Ref.…”

The quasi-SU(3) sequence of the positive parity νg 9/2 ,d 5/2 ,s 1/2 orbitals above the N = 40 shell gap are assumed to induce strong quadrupole collectivity in the neutron-rich Fe (Z = 26) and Cr (Z = 24) isotopes below the nickel region. In this paper the position and strength of these single-particle orbitals are characterized in the neighborhood of 68 Ni (Z = 28, N = 40) through the 66 Ni(d,p) 67 Ni one-neutron transfer reaction at 2.95 MeV/nucleon in inverse kinematics, performed at the REX-ISOLDE facility in CERN. A combination of the Miniball γ -array and T-REX particle-detection setup was used and a delayed coincidence technique was employed to investigate the 13.3-μs isomer at 1007 keV in 67 Ni. Excited states up to an excitation energy of 5.8 MeV have been populated. Feeding of the νg 9/2 (1007 keV) and νd 5/2 (2207 keV and 3277 keV) positive-parity neutron states and negative parity (νpf ) states have been observed at low excitation energy. The extracted relative spectroscopic factors, based on a distorted-wave Born approximation analysis, show that the νd 5/2 single-particle strength is mostly split over these two excited states. The results are also compared to the distribution of the proton single-particle strength in the 90 Zr region (Z = 40,N = 50).
