  The hyperfine interactions at the uranium site in the antiferromagnetic USb2
compound were calculated within the density functional theory (DFT) employing
augmented plane wave plus local orbital (APW+lo) method. We investigated the
dependence of the nuclear quadruple interaction to the magnetic structure in
USb2 compound. The result shows that the 5f-electrons have the tendency to be
hybridized with the conduction electrons.
