“…The theoretical studies reported in reference [22] are based on the experimental data of references [23][24][25] in which the lowest observed level of the positive parity yrast band is suggested to be the band head with a tentative spin assignment as 8 + and configuration {πh 11/2 ⊗ νh 11/2 }. In a recent experimental study [26], a positive parity side band was observed for the first time, and the lowest level of the positive parity yrast states was reassigned to have spin 9 + based on the systematics of odd-even staggering, in agreement with a previous study [27]. To investigate these bands theoretically, we couple two valence quasiparticles to 136 Nd which is treated as a rotor within the framework given in section 2.…”

A large wealth of data and a variety of models led to significant progress in understanding the spectra of deformed nuclei. However, a robust theoretical approach, which is less reliant on adjustable parameters is still elusive. Due to the scarcity of data, this drawback gets more pronounced while studying the exotic nuclei. With the motive to overcome this difficulty, we have developed the nonadiabatic quasiparticle approach for the description of rotational states in triaxial deformed odd–odd nuclei. The rotation-particle coupling is carried out utilizing an appropriate basis transformation such that the matrix elements of the odd–odd system can be written in terms of the rotor energies. This provides the advantage of studying the role of core more efficiently as compared to the conventional particle rotor model. The residual interaction between the valence proton and neutron is incorporated in two reliable ways, namely, the constant potential form and the zero-range interaction.

“…Based on constrained triaxial covariant density functional theory (CDFT) calculations [2], it has been suggested that multiple chiral doublet (Mχ D) bands can exist in a single nucleus [3][4][5][6][7][8]. To date, the chiral doublet bands, including Mχ D bands, have been reported in more than 40 nuclei in the A ≈ 80 [9,10], 100 [11][12][13][14][15][16][17][18], 130 [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35], and 190 [36][37][38][39][40][41][42] mass regions. For details, see recent reviews [43][44][45][46][47][48][49] or data tables [50].…”

High spin states in 127I were populated via 124Sn(7Li, 4nγ) fusion-evaporation reaction at Ebeam = 33 MeV. Level scheme of 127I has been updated by placing new γ-rays and also by confirming the spin/parity of several energy levels. Two new levels at Ex = 2628 and 3199 keV have been identified which are found to decay into the negative parity πh11/2 band. These two states and two earlier reported states at 3502 and 3989 keV have been interpreted as the γ-vibrational states on the basis of their decay pattern. Two positive parity three-quasiparticle bands above Iπ = 23/2+ states at 2901 and 3060 keV have been identified to be a possible candidate of chiral band. A comparison in the isotopic and isotonic chains reveals the possible existence of γ-vibration and chiral rotation in 123–127I.
