Levels in {sup 186,188}Os have been investigated using the ({sup 3}He,d) reaction with 30 MeV {sup 3}He beams. Absolute level-population cross sections have been determined, and angular distributions measured between 5 deg. and 50 deg. The 4{sub 3}{sup +} levels are observed to be some of the strongest populated states below 2 MeV excitation energy, and the magnitudes of the 5/2{sup +}[402]{sub {pi}}+3/2{sup +}[402]{sub {pi}} configuration extracted are in line with quasiparticle-phonon model predictions which state that the lowest-lying K{sup {pi}} = 4{sup +} band is predominantly a hexadecapole excitation.
