The perturbed angular-distribution method has been used to measure the g factor of the tau = 122(10)-nsec fission isomer in /sup 237/Pu. To eliminate unwanted perturbations, a special cubic nonparamagnetic alloy, /sup 235/UIr/sub 2/, was heated to 950 /sup 0/C and used as the target. The quantities measured were A/sub 22/ = +0.21(6) and g = -0.45(3). The g factor is consistent with the I = 3,2 ground state of the 871 1/2/sup +/ Nilsson orbital, and the fission anisotropy is consistent with K = 1/2 at the second saddle point.
