description

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 5d106s S1y2 ! 5d106p P3y2 optical transition. The nuclear moments of both states and the mean square charge radius changes were measured. The magnetic moments were determined to be m 184g I­5 ­ 12.07s2dmN and m I­2 ­ 11.44s2dmN and the spectroscopic quadrupole moments to be Q 184g s ­ 14.65s26db and Q184m s ­ 11.90s16d b. A difference in the mean square charge radius dkr2 c l184g,184m ­ 20.036s3d fm2 was found. [S0031-9007(97)03992-6]
