“…The evidence of the chiral doublet bands was first observed in 2001 [2]. So far, around 40 candidates of chiral doublet bands have been reported in A ∼ 80 [3,4], 100 [5][6][7][8][9][10], 130 [2,[11][12][13][14][15][16] and 190 [17,18] mass regions experimentally, see [19][20][21] for reviews. Theoretically, the chiral doublet bands are studied by the particle rotor model (PRM) [1,[22][23][24][25], the titled axis cranking (TAC) model [1,[26][27][28][29], the TAC plus random phase approximation [30], the collective Hamiltonian [31,32], and the interacting boson-fermion-fermion model (IBFFM) [33][34][35].…”

The pairing-plus-quadrupole Hamiltonian is diagonalized in a symmetry restored basis, i.e., the triaxial quasiparticle-states with angular momentum and particle number projections, and applied for chiral doublet bands in 128 Cs. The observed energy spectra and electromagnetic transition probabilities are reproduced well without introducing any parameter. The orientation of the angular momentum in the intrinsic frame is investigated by the distributions of its components on the three principle axes as well as those of its tilted angles. The evolution of the chirality with spin is illustrated and the chiral geometry is demonstrated in the angular momentum projected model for the first time.

Specific features and symmetries for magnetic and chiral bands in nuclei

Magnetic and chiral bands have been a hot subject for more than twenty years. Therefore, quite large volumes of experimental data as well as theoretical descriptions have been accumulated. Although some of the formalisms are not so easy to handle, the results agree impressively well with the data. The objective of this paper is to review the actual status of both experimental and theoretical investigations. Aiming at making this material accessible to a large variety of readers, including young students and researchers, I gave some details on the schematic models which are able to unveil the main features of chirality in nuclei. Also, since most formalisms use a rigid triaxial rotor for the nuclear system's core, I devoted some space to the semi-classical description of the rigid triaxial as well as of the tilted triaxial rotor. In order to answer the question whether the chiral phenomenon is spread over the whole nuclear chart and whether it is specific only to a certain type of nuclei, odd-odd, odd-even or even-even, the current results in the mass regions of $A\sim 60,80,100,130,180,200$ are briefly described for all kinds of odd/even-odd/even systems. The chiral geometry is a sufficient condition for a system of proton-particle, neutron-hole and a triaxial rotor to have the electromagnetic properties of chiral bands. In order to prove that such geometry is not unique for generating magnetic bands with chiral features, I presented a mechanism for a new type of chiral bands. One tries to underline the fact that this rapidly developing field is very successful in pushing forward nuclear structure studies.Comment: 80 pages, 22 figure

“…40, the lifetimes of the excited levels for the lowest two nearly degenerate bands of 106 Ag are also measured using the Doppler-shift attenuation method. 41 The authors argued that similar transition rates but different moments of inertia observed in the doublet bands of 106 Ag may contain a novel observation for a nearly degenerate doublet band. 41…”

“…37 In A ∼ 100 mass region, the lifetime measurements have been performed for 103,104 Rh, 38 102 Rh 39 and 106 Ag. 40,41 Although the chiral partner bands have energies close to each other, it is rare to observe a crossing between them. Therefore, crossing of candidate chiral bands is important as a test of the onset of static chirality.…”

“…In particular the nucleus 106 Ag, as one of only two known examples of candidates which actually cross, has been investigated by many groups. 40,41,43,[57][58][59] In a recent work, 40 the high spin states in 106 Ag were populated using 96 Zr( 14 N, 4n) reaction with the γ-detector array AFRODITE at iThemba LABS. The level scheme of 106 Ag has been extended, and three negative-parity bands, labeled as bands 1, 2 and 3, have been observed to high spins.…”

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.
