“…Rotational doublet-band candidates for chiral structures have been observed mostly in two regions of the nuclear chart: around 134 Pr (see, e.g., Refs. [3][4][5][6][7][8][9][10][11][12][13][14][15][16]) and around 104 Rh (see, e.g., Refs. [17][18][19][20][21][22]).…”

The high-spin structure of the 105 Ag nucleus has been studied by using the 100 Mo( 10 B, 5n) 105 Ag reaction to search for chiral doublet bands based on the three-quasiparticle πg 9/2 ν(h 11/2 ) 2 configuration. The level scheme of 105 Ag has been extended. New bands were found and the placement of the yrast πg 9/2 ν(h 11/2 ) 2 band was corrected. No side band to the yrast πg 9/2 ν(h 11/2 ) 2 band could be found in the present experiment. This observation indicates that the γ -soft shape in the 106 Ag changed to a more γ -rigid axially symmetric shape in the yrast 105 Ag configuration. However, a new pair of bands was observed to show the expected properties of a chiral doublet structure.

“…Extensive experimental studies were made to search for chiral bands in transitional A ∼ 130 nuclei, which are known to be soft with respect to triaxial deformation. As a result, candidate chiral doublet bands based on the πh 11/2 ⊗ νh 11/2 configuration were reported in several N = 73 [43], N = 75 [19], and N = 77 [44] isotones, such as in odd-odd 57 La and 55 Cs nuclei with the Fermi level near the bottom of the πh 11/2 subshell and near the top of the νh 11/2 subshell. Following this systematics, one would then expect that such bands should exist in 128 I with N = 75, Z = 53.…”

High-spin level scheme of doubly odd128I

High-spin states in the odd-odd 128 I have been studied experimentally using the 124 Sn( 7 Li, 3nγ ) 128 I reaction at beam energies of 28 and 32 MeV. A level scheme built on the known T 1/2 = 175 ns, (6 − ) isomer has been established. The low-lying states in the level scheme have been proposed to be associated with the πd 5/2 ⊗ νh 11/2 and πg 7/2 ⊗ νh 11/2 two-quasiparticle excitations. The strongly populated negative-parity states, forming a bandlike structure, have been assigned to be based on the πg 7/2 ⊗ νh 11/2 configuration. The πh 11/2 ⊗ νh 11/2 multiplet 9 + , 10 + , and 11 + members have been identified according to the systematics of the corresponding level structures observed in the lighter odd-odd iodine isotopes. The two-quasiparticle configuration assignments are supported by the nucleon pair approximation and empirical shell-model calculations.

“…11,12 Recently, based on TAC with single-j shell, a new collective Hamiltonian to describe the chiral rotation and vibration was proposed and applied to the system with one h 11/2 proton particle and one h 11/2 neutron hole coupled to a triaxial rotor. 13 Experimentally, the evidences of chiral doublet bands have been extensively reported in the A ≈ 80, 100, 130 and 190 mass regions [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] (see Refs.

Progresses of the chirality in atomic nuclei are reviewed, in particular, the recently proposed collective Hamiltonian based on tilted axis cranking approach to describe chiral vibration and rotation modes, and the experimental achievements for chirality and multiple chiral doublets, i.e., in 106 Ag, 133 Ce and 103 Rh. The first experimental evidences of multiple chiral doublet bands with distinct and identical configuration found in 133 Ce and 103 Rh are discussed in detail.
