Resonant x-ray scattering experiments have been performed on a high-quality single crystal of URu2Si2, cut with a [101] direction specular. Data have been collected at the uranium M4 absorption edge below the hidden-order transition temperature, TH=17.5 K, exploring the region of the reciprocal space plane [H0L] with 1≤H≤1.85 and 1.8≤L≤2.1. Within the sensitivity of our measurements, the results obtained exclude electric quadrupoles of any symmetry as a hidden-order parameter with a propagation vector in the explored region.
