“…The present work reports on the negative parity part of the level scheme, focusing on the rotational bands with π h 9/2 ⊗ νi 13/2 −2 nature. Preliminary results were published in [68][69][70][71]. The present paper supersedes these publications.…”

High-spin states in 193 Tl were studied and the level scheme was revised and extended including the observation of new rotational bands. A surprising competition between bands built on the same π h 9/2 ⊗ νi 13/2 −2 nucleon configurations is observed. It is suggested that it is generated by two different rotational modes of this triaxial nucleus: (i) a rotation around the intermediate nuclear axis, producing a pair of chiral symmetry bands, and (ii) a rotation around the long nuclear axis, producing a third band with lower alignment.

“…Recent experimental data taken at iThemba LABS with the AFRODITE array led to a revision and an extension of the previous level scheme of 193 Tl [17]. In particular, several sets of rotational bands, built on πh 9/2 ⊗ νi −n 13/2 configurations with n = 2, 4 were identified [18,19]. The bands are labelled according to the number of quasiparticles involved and according to their relative excitation energy at low spins, in a similar way as in 194 Tl.…”

Sets of near-degenerate rotational bands built on configurations involving πh 9/2 particle and νi 13/2 holes were observed in the neighbouring 193,194 Tl isotopes. Such sets of bands, involving particle and hole configurations and occurring in nuclei with triaxial shape, are caused by chiral symmetry formed in angular momentum space. Each nuclear chiral system is expected to generate a pair of near-degenerate partner bands. However, several sets of three partner bands were observed in these Tl isotopes, raising questions whether one or two chiral systems are formed, and which two bands are partners in the chiral pair. Many-particle-rotor model calculations reproduce well the features of the observed negative-parity bands in 193,194 Tl and support the suggested chiral geometry of the angular momenta.

“…To test the theoretical prediction of chirality in atomic nuclei, significant effort has been devoted to further exploring this interesting phenomenon. Thus far, such chiral doublet bands have been reported in the 80 [2][3][4], 100 [5][6][7][8][9][10][11][12], 130 [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29], and 190 [30][31][32][33][34][35][36] mass regions of the nuclear chart. For details, see recent reviews on nuclear chirality and related topics [37][38][39][40][41][42][43][44][45] or data tables [46].…”

Recent progress regarding multiple chiral doublet bands ( ) is reviewed from the experimental and theoretical perspectives. In particular, the experimental findings, theoretical predictions, selection rule for electromagnetic transitions, with octupole correlations, and some related topics are highlighted. Based on these discussions, it is of great scientific interest to search for the other , as well as possible chiral wobblers, chirality-parity quartet bands, and chirality-pseudospin triplet (or quartet) bands in the nuclear system.
