Excited states in {sup 182}Pt have been studied via the heavy-ion reactions {sup 170}Yb({sup 16}O,4n), {sup 162}Dy({sup 24}Mg,4n), and {sup 163}Dy({sup 24}Mg,5n). {gamma}-ray coincidence measurements were performed with arrays of HPGe detectors at the McMaster University Tandem Accelerator Laboratory ({sup 16}O-induced reaction) and the Institut de Physique Nucl{acute e}aire, Orsay ({sup 24}Mg-induced reactions). The ground-state rotational band has been extended to I=26{h_bar}, and six new band structures have been identified and assigned quasiparticle configurations. The {gamma}-vibrational band and the band built upon the first excited 0{sup +} 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. {copyright} {ital 1997} {ital The American Physical Society}
