High-k Structures in 124Cs

High spin states in the odd-odd nucleus 124Cs have been investigated through the fusion-evaporation reaction 116Sn(11B, 3n)l24 Cs with a beam energy of 45 MeV. A new rotational band is established and assigned as the high-k configuration of πg9/2140419/2+ ⊙vh 11/2[523]7/2-. Some structures linking t...

Summary:High spin states in the odd-odd nucleus 124Cs have been investigated through the fusion-evaporation reaction 116Sn(11B, 3n)l24 Cs with a beam energy of 45 MeV. A new rotational band is established and assigned as the high-k configuration of πg9/2140419/2+ ⊙vh 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 Iπ is not changed.
