Excited states in 182Pt have been studied via the heavy-ion reactions 170Yb(16O,4n), 162Dy(24Mg,4n), and 163Dy(24Mg,5n). γ-ray coincidence measurements were performed with arrays of HPGe detectors at the McMaster University Tandem Accelerator Laboratory (16O-induced reaction) and the Institut de Physique Nucléaire, Orsay (24Mg-induced reactions). The ground-state rotational band has been extended to I=26ħ, and six new band structures have been identified and assigned quasiparticle configurations. The γ-vibrational band and the band built upon the first excited 0+ state have also been extended. Properties of the rotational bands are compared with cranked-shell-model and total-Routhian-surface calculations. Evidence concerning shape coexistence at low spin and band crossings at high spin is discussed.
