“…In the odd-odd Sb isotopes, the yrast bands of 110 Sb(N = 59) and 112 Sb(N = 61) are predicted to exhibit the shear mechanism [22]. However, the recent lifetime measurements [23] for 112 Sb indicate that the B(M1) shows 4. (Color online) The angular momentum composition of the proton j π and neutron j ν , and total angular momentum I in PRM for band 1 are illustrated at spins I = 8h, 12h, and 16h. a small decrease with increasing spin.…”

Excited states of 118 Sb were populated via the 116 Cd( 7 Li,5n) 118 Sb fusion-evaporation reaction at a beam energy of 50 MeV. The previously known level scheme has been considerably extended, and about 36 new transitions were added into the level scheme of 118 Sb. One new rotational band has been identified, and assigned the πg −1 9/2 ⊗ νg 7/2 configuration. The configuration-fixed constrained triaxial relativistic mean-field approaches and the particle-rotor model calculations are employed for analysis of the level structure of 118 Sb.

“…Considering the systematic behavior of magnetic rotation, we infer 80 Rb could be a candidate nucleus with MR bands. Similarly, the candidates are also suggested in 108 Ag, 137 Ce, 135,140 Nd, 140 Sm, 190 Pb, and 196,201 Bi. Moreover, it is interesting that in nuclei with MR 104−106 Ag, 105 Rh, 136−138 Nd, and 194 Tl there are reported also chiral bands constructed on similar particle and hole geometries [325].…”

The magnetic and antimagnetic rotational bands are systematically investigated in the present work. Up to now, 253 magnetic rotational bands and 40 antimagnetic rotational bands have been reported in 123 nuclei and 29 nuclei, respectively. The experimental data for these bands are collected and collated, including the level energy, γ-ray energies, spin I, magnetic dipole reduced transition probability B(M1), electric quadrupole reduced transition probability B(E2), B(M1)/B(E2), and J (2)/B(E2), etc. In addition, following the presentation of the kinematic moment of inertia J (1), dynamic moment of inertia J (2), and I versus rotational frequency ω, as well as energy staggering parameter S(I), B(M1), B(E2), B(M1)/B(E2), and J (2)/B(E2) versus I in A ∼ 60, 80, 110, 140, and 190 mass regions, a discussion is provided in detail. Based on the systematic studies, the main features of magnetic and antimagnetic rotational bands are summarized. Furthermore, some nuclei are also predicted to be candidates for magnetic or antimagnetic rotation.

“…Decoupled ΔJ=2 bands have been observed in the even-A Sb isotopes using large Gamma Detector arrays coupled to channel selection devices such as charged-particle and neutron detectors and fragment mass analyzers. Experimental results on the study of the 106−118 Sb nuclei are reported in [34,[60][61][62][63][64][65][66]. High-spin-states in the neutron deficient 106 Sb are essentially spherical in nature and are explained within the framework of the shell model using a realistic effective nucleon-nucleon interaction.…”

A brief review of intruder rotational bands and magnetic rotation in theA= 110 mass region

Nuclei in the A∼110 mass region exhibit interesting structural features. One of these relates to the process by which specific configurations, built on the excitation of one or more protons across the Z=50 shell-gap, manifest as collective rotational bands at intermediate spins and gradually lose their collectivity with increase in spin and terminate in a non-collective state at the maximum spin which the configuration can support. These bands are called terminating bands that co-exist with spherical states. Some of these bands are said to terminate smoothly underlining the continuous character of the process by which the band evolves from significant collectivity at low spin to a pure particle-hole non-collective state at the highest spin. The neutron-deficient A∼110 mass region provides the best examples of smoothly terminating bands. The present experimental and theoretical status of such bands in several nuclei with 48Z52 spanning the 106A119 mass region have been reviewed in this article. The other noteworthy feature of nuclei in the A∼110 mass region is the observation of regular rotation-like sequences of strongly enhanced magnetic dipole transitions in near-spherical nuclei. These bands, unlike the well-studied rotational sequences in deformed nuclei, arise from a spontaneous symmetry breaking by the anisotropic currents of a few high-j excited particles and holes. This mode of excitation is called magnetic rotation and was first reported in the Pb region. Evidence in favor of the existence of such structures, also called shears bands, are reported in the literature for a large number of Cd, In, Sn and Sb isotope with A∼110. The present article provides a general overview of these reported structures across this mass region. The review also discusses antimagnetic rotation bands and a few cases of octupole correlations in the A=110 mass region.
