The ²³⁵U (I=7/2) NMR for magnetic uranium sites with 5f-electronshas been first observed in the antiferromagnetic state of UO₂.The hyperfine field is estimated to be 252.3 ± 0.5 T.Well articulated quadrupole splittings have also been observedwith |e²qQ(3cos²θ-1)/h| = 392 ± 11 MHz. This indicates the presence of an electric field gradient produced by the Γ₅-ground state for 5f-electrons in the magnetic ordering.
