Resonance ionization spectroscopy (RIS) was performed on desorbed Au, and the complete hyperfine spectrum of both isomeric and ground states of the short lived 184Au nucleus has been recorded from the 5d106s2S1/2→5d106p2P3/2 optical transition. The nuclear moments of both states and the mean square charge radius changes were measured. The magnetic moments were determined to be μI = 5184g = +2.07(2)μN and μI = 2184m = +1.44(2)μN and the spectroscopic quadrupole moments to be Qs184g = +4.65(26)b and Qs184m = +1.90(16)b. A difference in the mean square charge radius δ〈rc2〉184g,184m = -0.036(3)fm2 was found.
