“…The target was placed in the center of the Gammasphere array [45], comprising 101 Compton-suppressed high-purity germanium (HPGe) detectors. The energy and efficiency for each HPGe detector was calibrated using standard 56 Co, 152 Eu, 182 Ta, and 243 Am sources. The reaction products were transported through the Argonne Fragment Mass Analyzer (FMA) [46] and were dispersed at the focal plane of the instrument according to their mass-to-charge ratio, M/q.…”

“…Remarkably, partial proton and alpha decays out of some of these bands have been reported in 56 Ni and 58 Ni. In contrast, no experimental evidence for collective excitations has been reported thus far for Ni isotopes closer to the N = 40 subshell closure.…”

“…Specifically, much attention has been devoted to documenting the evolution of shell structure with neutron number N in nuclei located above doubly-magic 48 Ca. In neutron-rich 52 Ca [1], 54 Ti [2], and 56 Cr [3], a new subshell gap was established at N = 32, based on systematic studies of 2 + 1 energies and B(E2;2 + 1 →0 + 1 ) transition strengths [4][5][6][7]. Indications of an N = 34 subshell closure have been found in 54 Ca [8].…”

“…In the Ni isotopic chain, the Z = 28 shell closure stabilizes a spherical shape near the ground state in nuclei between 56 Ni and 78 Ni and the level sequences at low and moderate spin are described well by shell-model calculations [26]. Here, the filling of the neutron p 3/2 , f 5/2 , p 1/2 , and g 9/2 orbitals determines mostly the structure of low-energy excitations as shown quantitatively in the study of Ref.…”

“…Rotational sequences have been reported at moderate and high spin in some of the lighter even-even Ni isotopes: highly deformed and even superdeformed bands, built upon lower-lying single-particle excitations, have been observed in doubly-magic 56 Ni [32,33], as well as in 57 Ni [34,35], 58 Ni [36][37][38], 59 Ni [39], and 60 Ni [40,41]. Remarkably, partial proton and alpha decays out of some of these bands have been reported in 56 Ni and 58 Ni.…”

Three collective bands, built upon states of single-particle character, were identified. For two of the three bands, the transition quadrupole moments were extracted, herewith quantifying the deformation at high spin. The results have been compared with shell-model and cranked Nilsson-Strutinsky calculations. Despite the Z = 28 shell closure and the approach to the purported N = 40 subshell, the 63 Ni isotope is able to sustain collective excitations at moderate and high spin.
