Abstract
High spin states in the odd-odd nucleus 124 Cs have been investigated through the fusion-evaporation reaction 116 Sn( 11 B, 3n) 124 Cs with a beam energy of 45 MeV. A new rotational band is established and assigned as the high- k configuration of π g 9/2 [404]9/2 + ⊗ν h 11/2 [523]7/2 − . Some structures linking to this band have also been observed. According to the results of the excitation energy systematics, the lowest level of this band is assigned as 9 - , and the 8 - isomer bandhead has not been observed. Another isomer with a half life of 6.3 s has also been observed with its new decay paths established. Its excitation energy is raised by 79 keV, but its I π is not changed.
