We report measurement of the g-factor for the 11/2 − isomeric state at 535 keV in 133 La, employing the time differential perturbed angular distribution technique (TDPAD). This isomer was populated in the reaction 126 Te( 11 B, 4n) 133 La at beam energy of 52 MeV. From the observed nuclear spin precession, analysed through combined, magnetic dipole and electric quadrupole hyperfine interactions, we obtain the g-factor for the 11/2 − state as g = 1.16 ± 0.07. In addition, this analysis provides the spectroscopic quadrupole moment |Q| = 1.71 ± 0.34 b, yielding the deformation parameter β = 0.28 ± 0.10. Further, we have performed theoretical calculations using the large-scale shell model and the Monte Carlo shell model. The results successfully describe the low-lying levels and the band structures of 133 La, and the calculated g-factor compares well with the values obtained from our experiment. The dominant configuration of 11/2 − isomeric state in 133 La is inferred to be π(h 11/2 ) ⊗ 132 Ba(0 + ).
