Abstract

The band built on the Kπ=8-,T1/2=9.4 ms isomer of Ba130 has been identified, filling the gap in the systematics of the dipole bands built on the 8- isomers in the N=74 isotones from Xe128 to Gd138. The use of the GALILEO array in conjunction with its ancillaries EUCLIDES and Neutron Wall, helped to firmly place the newly identified transitions on top of the long-lived isomer. The extracted gK and gR gyromagnetic factors are in agreement with the 7/2+[404] - 9/2-[514] two-neutron Nilsson configuration. Particle-rotor model calculations give an understanding of the limited degree of K mixing. The experimental information on the Kπ=8- isomer of Ba130 is now the most complete among the K isomers of the N=74 isotones.
