Thakur, PKumar, VBhati, A.K.Bedi, S.C.Singh, R.P.Bhowmik, R.K.Stuchbery, Andrew2015-12-070556-2813http://hdl.handle.net/1885/21701The nuclear g-factors of the one-quasiparticle isomeric state 92- at 165.8 keV and the three-quasiparticle isomeric state 212- at 1713.2 keV in Ta173 nuclei have been measured using the time differential perturbed angular distribution technique. The nuclear reaction Ho165(C12, 4nγ)Ta173 was used to populate these isomeric states, and the recoiling Ta173 nuclei were implanted into a thick tantalum backing in the presence of a 7.04(4) kG external magnetic field. The measured value g(92-) = +0.591(18) shows that the 92- isomeric state is not a pure single-particle state but may have a collective contribution due to the octupole excitation of the core. Based on the measured value g(212-) = + 0.620(15) and multi-quasiparticle calculations, the 212- isomeric state is assigned a mixed configuration: π3{92-[514], 72+[404], 52+[402]} (39%) and π1{72+[404]} ν2{72-[514], 72+[633]} (61%).200610.1103/PhysRevC.74.0343292015-12-07
