The isomeric state of 73 As (426 keV, 5.8 jusec) was produced and aligned by the reaction 71 Ga (a,2n) in a liquid metal target. The anisotropics of the depopulating y-rays were measured vs. the dc magnetic field applied perpendicular to the beam-detector plane. From the attenuation and rotation, we obtain g= +1.03 ± 0.11. Limits of <5 2 < 10-2 can be set to the multipole admixtures in both ^-transitions. The same technique was applied to the 123 /usee isomer of 206 Pb (2200 keV) produced by 204 Hg (a,2n). After estimating the relaxation time, g =-(0.035 + 0.020) is obtained.
