gfactors of92−and232+isomeric states in129Ba

The time differential perturbed angular distribution (TDPAD) technique has been used to measure the g factor of the 173 keV 9/2(-) and 2162 keV 23/2(+) isomeric states in Ba-129 with respect to the known value of the g factor, -0.159(5), of the 10(+) isomeric state in Ba-132. The measured internal magnetic field at 132Ba in Fe at room temperature is -6.0(2) T. The extracted g(9/2(-)) value, -0.192(6), is consistent with the pure nu 9/2(-)[514] Nilsson configuration while the g(23/2(+)) value, -0.233(7), corresponds to the proposed three-quasineutron configuration 5/2(+)[402]circle times 7/2(-)[523]circle times 11/2(-)[505] with the admixture of nu 7/2(+)[404]circle times 7/2(-)[523]circle times 9/2(-)[514] configuration.
