Hyperfine-structure parameters and isotope shift of the 9/2(-) isomeric state in Au-187 relative to Au-197 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 Au-187 confirms the occurrence of the shape coexistence in Au-187 proposed earlier from the analysis of the nuclear spectroscopic data and particle plus triaxial rotor calculations. The analysis of the magnetic moment supports the previously proposed 9/2(-), 1/2(-)[541] assignment at moderate prolate deformation for Au-187(m).
