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