摘　　要：High-spin states in182Au have been produced and studied via the152Sm(35Cl,5nγ)182Au reaction. The level scheme consisting of the πh 9/2?νi 13/2 and πi 13/2?νi 13/2 bands has been established for the first time. The low spin signature inversion in both bands has been found. The observed signature inversion phenomena can be interpreted qualitatively using the pairing and deformation self-consistent cranked Wood-Saxon calculations.High-spin states in 182Au have been produced and studied via the 152Sm(35Cl,5nγ)182Au reaction.
