Direct AFNMR studies of 235U as well as of 121Sb and 123Sb nuclear spins have been carried out in the antiferromagnetic state of USb2. The central (±1/2) 235U peak found at 217.2 MHz passes several identification tests, including the expected very low rate of broadening in an applied field. The 235U hyperfine constant found, 147 T/μB, is within the expected range. This is the first reported observation of 235U NMR in a conducting host material.
