“…3, and their placements are also confirmed in the present work. Indeed, this work validates almost all placements within this structure and agrees with the multipolarity assignments for the newly identified transitions associated with the positive-parity levels reported by Rai et al [21]. It, however, differs somewhat in the placement and multipolarity assignments for the 738-, 1264-, and 1537-keV transitions linking the negativeparity states.…”

“…Previous spectroscopic studies of 66 Zn were undertaken in Refs. [15][16][17][18][19] and, very recently, by Bala et al [20] and Rai et al [21]. In the latter, a collective structure was observed up to termination accompanied by a crossing with the ground-state band around spin 6 h. These observations have been confirmed and complemented with large-scale shell-model calculations carried out in the present work.…”

“…The observations are confirmed here. While the present work was in preparation, Rai et al [21] and Bala et al [20] independently reported the observation of additional new excited states in 66 Zn. Using a heavy-ion induced reaction, Rai et al [21] added positive-parity levels connected by the 519-, 1089-, 1367-, 1399-, 1576-, and 1786-keV transitions above the 12 + 1 state, and two new transitions (1408 and 1801 keV) in the negative-parity part, as well as the 644-and 828-keV transitions linking the two sequences.…”

This established the structure up to an excitation energy of ≈12.3 MeV and a spin of ≈17 h. These transitions, some of which are highlighted with red squares in the total projection spectrum displayed in Fig.…”

“…For example, the 738-keV transition, of dipole character, is placed in Ref. [21] as feeding directly the 6 − 1 level at 4074 keV, bypassing the 4250-keV 7 − 1 state and thus, in anticoincidence with the 176-keV γ ray. In the present work, the 738-keV transition is found to directly populate the 8 − level at 5338 keV, which is in turn depopulated by two transitions; a 1264-keV quadrupole one (reported as dipole in Ref.…”

Single-particle and collective excitations in 66 Zn have been investigated via the multinucleon transfer reaction, 26 Mg( 48 Ca, α4nγ ) using the Gammasphere multidetector array and the Fragment Mass Analyzer. In addition to confirming and complementing the previously known low-spin structure, a new quasirotational band comprising several stretched E 2 transitions has been established to high spins. However, due to fragmentary nature of its decay, it was not possible to link this sequence to the low-lying states and, thus, determine the absolute excitation energies, spins, and parities unambiguously. Large-scale shell-model calculations employing the JUN45 and jj44b effective interactions are able to successfully describe the low-spin structure and herewith confirm that it is dominated by single-particle excitations. The newly established rotational cascade is compared with known superdeformed bands in the A ≈ 60-70 mass region, and with results of calculations performed within the frameworks of the cranked shell model and the adiabatic and configuration-fixed constrained covariant density functional theory and the quantum particle-rotor model.

Based on the systematic studies for low-lying states of the odd-$A$ $\rm {}^{49-57}Mn$ isotopes, the ground-states inversion and the rotational properties of ground-state-based sequence are revealed and discussed. The energy levels of low-lying states and electromagnetic moments in odd-$A$ $^{49-57}$Mn isotopes have been well reproduced in shell-model calculations, and the above phenomena could be understood with obviously different occupation numbers in proton orbitals such as $\pi f_{7/2}$ and $\pi p_{3/2}$, which changes similarly with the obtained quadrupole deformation in covariant density functional theory~(CDFT). After considering the coupling of collective rotation and intrinsic single-particle motion, the available experimental magnetic moments in $\rm ^{53}Mn$ and adjacent nuclei can be well explained with CDFT. The present calculations suggest that the $5/2^-$ and $7/2^-$ states in $^{53}$Mn are formed by $\pi5/2^-[312]$ and $\pi7/2^-[303]$ respectively. Together with behavior of levels, this provides proofs for the level sequences of low-lying states in $\rm ^{53}Mn$ distinct from the $K^\pi=5/2^-$ rotational band in $^{49}$Cr and other odd-$A$ Mn isotopes.
