The candidate chiral doublet bands recently observed in 126 Cs have been extended to higher spins, several new linking transitions between the two partner members of the chiral doublet bands are observed, and γ−intensities related to the chiral doublet bands are presented by analyzing the γ−γ coincidence data collected earlier at the NORDBALL through the 116 Cd( 14 N, 4n) 126 Cs reaction at a beam energy of 65 MeV. The intraband B(M 1)/B(E2) and interband B(M 1) in /B(M 1) out ratios and the energy staggering parameter, S(I), have been deduced for these doublet bands. The results are found to be consistent with the chiral interpretation for the two structures. Furthermore, the observation of chiral doublet bands in 126 Cs together with those in 124 Cs, 128 Cs, 130 Cs and 132 Cs also indicates that the chiral conditions do not change rapidly with decreasing neutron number in these odd-odd Cesium isotopes.

High-spin states in 162 Ho have been populated in the reaction 160 Gd( 7 Li, 5n) at a beam energy of 49 MeV. The K π = 1 − band, the low-K Gallagher-Moszkowski (GM) partner band of known high-K(K π = 6 − ) band, based on the configuration π 7/2 − [523] ⊗ ν5/2 + [642], and the K π = 6 + band, the high-K GM partner band of known low-K(K π = 1 + ) band, based on the configuration π 7/2 − [523] ⊗ ν5/2 − [523], have been identified. GM splitting energies, defined as E GM = E K int − E K int , 80 keV and −135 keV were extracted from these two sets of GM doublet bands, respectively. They are comparable with 65 keV and −145 keV, reported recently by Hojman et al. for the corresponding configurations π 7/2 − [523] ⊗ ν5/2 + [642] and π 7/2 − [523] ⊗ ν5/2 − [523] in 164 Ho, respectively.

High spin states of 122 Cs are reinvestigated through the 116 Sn( 10 B, 4n) 122 Cs reaction at the beam energy of 54 MeV. Two new levels are added to the lower side of the most strongly populated band and the previously proposed 488 keV linking transition between the two observed bands is replaced by the 95 keV linking transition. As a result of these new observations, it becomes reasonable to assign the most strongly populated band in 122 Cs as the π h 11/2 ⊗ νh 11/2 yrast band.
