在USb 2的反铁磁态下，对235 U以及121 Sb和123 Sb核自旋进行了直接AFNMR研究。在217.2 MHz处发现的中心（\（\pm\frac{1}{2}\））235 U峰通过了几个鉴定测试，包括在外加磁场中预期的非常低的展宽率。发现的235 U超精细常数147 T/µ B在预期范围内。这是首次报道的观察到的235 U NMR在导电主体材料。
Direct AFNMR studies of 235 U as well as of 121 Sb and 123 Sb nuclear spins have been carried out in the antiferromagnetic state of USb 2 . The central (\(\pm\frac{1}{2}\)) 235 U peak found at 217.2 MHz passes several identification tests, including the expected very low rate of broadening in an applied field. The 235 U hyperfine constant found, 147 T/µ B , is within the expected range. This is the first reported observation of 235 U NMR in a conducting host material.
