In order to investigate the local symmetry at the Si(4e)-site above and below hidden order temperatureTO=17.5 K in URu2Si2, we have carried out73Ge-nuclear magnetic resonance (NMR) measurement on 10%73Ge-substituted sample URu2(Si0.9Ge0.1)2. The specific heat measurement on the present sample shows a clear second-order transition, indicating that the hidden order is still a bulk property. Besides, equally split73Ge-NMR lines due to the nuclear quadrupole interaction gives evidence for fairly uniform electric-field gradient at the Ge-substituted sites, Although this is the first attempt to investigate the local symmetry at the 4e-site by proving electric interactions, no evidence for symmetry lowering belowTOhas been obtained at present.
