Abstract: 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. The analysis of the magnetic moment supports the previously proposed 9/2⁻, 1/2⁻ [541] assignment at moderate prolate deformation for ¹⁸⁷Au^m.
