Abstract
Low-lying states in the odd-odd light gold isotope ¹⁸²Au have been populated by the decay of the ¹⁸²Hg nuclei. Level energies, spin and parity values were determined using on-line -ray and e^- spectroscopy measurements. No isomeric state with a long half-life was found in the ¹⁸²Au nucleus. Spin and parity = 2⁺ can be very likely assigned to the ¹⁸²Au ground state.
