69,71Ga NMR/NQR studies have been performed on a single crystal of the transuranium superconductor PuRhGa5 with Tc ≃ 9 K. The spin-lattice relaxation rate 1 / T1 reveals that PuRhGa5 is an unconventional superconductor having an anisotropic superconducting gap. Moreover, Korringa behavior ( 1 / T1 T = const. ) is observed in the normal state below ∼ 30 K. This result suggests that the superconductivity sets in after the formation of a Fermi liquid state in this compound.
