Structure of the $4^{+}_{3}$ States in $^{186,188}$Os

The structures of 4$^{+}_{3}$ states in the Os nuclei have been the subject of debate for the past several decades. Based on measured B(E2) values, they were interpreted in $^{186-192}$Os as K$^{\pi}$=4$^{+}$ two-phonon $\gamma$ vibrations, whereas inelastic scattering results, and single-proton transfer (d,$^{3}$He) and (t,$\alpha )$ imply a hexadecapole phonon description. Uncertainties in the (t,$\alpha )$ reaction mechanism, however, were cited as preventing a firm conclusion based on those data. To help clarify the nature of these K$^{\pi }$=4$^{+}$ bands, we have performed a ($^{3}$He,d) stripping reaction on targets of $^{185,187}$Re using 30 MeV $^{3}$He beams provided by the MP-tandem facility of the LMU/TUM in Garching. With an energy resolution of 13 keV, the deuterons were analyzed at 9 angles ranging from 5$^{\circ}$ to 50$^{\circ}$ with the Q3D spectrograph, and absolute cross sections were obtained for levels up to 3 MeV in excitation energy. Preliminary results will be presented.
