“…Compared with the four-quasiparticle bands in 106 Ag [5] and 108 Ag [34], band F has been proposed to originate from the fourquasiparticle πg −1 9/2 ⊗ ν(g 7/2 /d 5/2 )(h 11/2 ) 2 configuration.

“…At the band head, the proton and neutron shear blades are almost perpendicular to each other owing to the repulsion of the particle and hole. Such bands have been observed in Rh, Ag, Cd, In, Sn, and Sb isotopes [4][5][6][7]. In addition, for the triaxial nucleus, a left-or a right-handed system can be constructed by the coupling of the high-j neutron particle and proton hole with the core rotation angular momentum vector.…”

High-spin level structure of the doubly odd nucleus104Ag

The high-spin level structure of the doubly odd nucleus 104 Ag has been investigated via the 97 Mo( 11 B, 4n) 104 Ag reaction at a beam energy of 50 MeV. The newly established level scheme includes lower-lying two-quasiparticle states and several higher-lying bands. Two positive-parity bands associated with the πg −1 9/2 ⊗ νd 5/2 and πg −1 9/2 ⊗ νg 7/2 configurations are extended significantly. Based on the comparison with the analogous structures in neighboring nuclei and the features of nuclear chirality, the negative parity bands are suggested as candidate chiral doublet bands with the πg −1 9/2 ⊗ νh 11/2 configuration.

“…Magnetic rotational or antimagnetic bands have been identified in Rh, Ag, Cd, In, Sn, and Sb isotopes in the A ≈ 110 mass region where the nuclei involve coupling of one or more proton holes in the high-g 9/2 orbitals with neutrons in the low-g 7/2 , d 5/2 , and h 11/2 orbitals. Magnetic rotational bands are also expected in 107 Ag, in addition to 103−106 Ag [3][4][5][6][7] and 109 Ag [8] in Ag isotopes. The level scheme of 107 Ag has been reported previously [9][10][11].…”

The excited states in 107 Ag were populated through the heavy-ion fusion evaporation reaction 100 Mo ( 11 B, 4n) 107 Ag at a beam energy of 46 MeV. Lifetimes of high-spin states in 107 Ag have been measured through the Doppler shift attenuation method. The deduced B(M1) values, gradually decreasing with increasing spin, clearly demonstrate that both the yrast positive-parity band and the yrast negative-parity band in 107 Ag are magnetic rotation bands. Furthermore, experimental deduced B(M1) values for the yrast positive-parity band are compared with the predictions of the particle rotor model. The approximate agreement between theoretical calculations and experimental results further confirms the mechanism of magnetic rotation for the yrast positive-parity band. In addition, a systematic investigation shows the evolution of the magnetic rotation mechanism in the A ≈ 110 mass region.

“…So far, many fascinating phenomena such as core excitation, magnetic rotation, chiral rotation, and so on, have been found to occur for nuclei with mass A ∼ 110 in the proximity of the Z = 50 spherical shell [1][2][3][4][5][6]. Moreover, exotic nuclear structures such as highly deformed states and chiral rotational bands have been observed in nuclei with A ∼ 130 and Z ∼ 60 [6][7][8].…”

High-spin states in 126 I have been investigated by using in-beam γ -ray spectroscopy with the 124 Sn( 7 Li, 5n) 126 I reaction at a beam energy of 48 MeV. The level scheme of 126 I has been extended and modified considerably by adding about 80 new γ rays and establishing five new bands. The configurations have been tentatively assigned for the yrast, yrare, and other excited bands with the help of triaxial projected shell-model (TPSM) and cranked shell-model calculations. The first band crossing in the yrast band is found due to alignments of a pair of (h 11/2 ) 2 neutrons. The first and the second band crossings in the yrare band are caused by the alignments of a pair of (d 5/2 ) 2 protons and a pair of (h 11/2 ) 2 neutrons, respectively. Due to the successive excitations of two, four, and six quasiparticles, the alignments in the yrare band present a gigantic rising feature. The yrast band exhibits a signature inversion at low spins and becomes normal after a reversion spin of I rev = 14. The yrare band exhibits an abnormal signature inversion in which the signature inversion phase persists up to the highest spin. The signature inversions in 126 I are well reproduced and successfully interpreted by the TPSM calculations. Some features of chirality are found for the four-quasiparticle (4qp) part of the yrast band and the 4qp excited band 2.
