N2 - Hyperfine-structure parameters and isotope shift of the 9/2− isomeric state in 187Au relative to 197Au for the 267.6-nm atomic transition have been measured for the first time using the in-source resonance-ionization spectroscopy technique. The magnetic dipole moment and change in the mean-square charge radius for this 9/2− isomer have been deduced. The observed large isomer shift relative to the 1/2+ ground state in 187Au confirms the occurrence of the shape coexistence in 187Au proposed earlier from the analysis of the nuclear spectroscopic data and particle plus triaxial rotor calculations.
