Abstract

The (He-3, d) single-proton stripping reaction has been performed on targets of Re-185,Re-187 to investigate the structures of the 4(3)(+) states in Os-186,Os-188. The experiment employed 30 MeV He-3 beams, and the reaction products were analyzed with a Q3D spectrograph. Absolute cross sections were determined at nine angles between 5 degrees and 50 degrees for states up to approximately 3 MeV in excitation energy. Large 5/2(+)[402](pi) + 3/2(+)[402](pi) two-quasiparticle components are deduced for the 4(3)(+) levels of both isotopes. Their magnitudes are in agreement with calculations performed using the quasiparticle phonon model, which predicts a coexistence of a large hexadecapole with a smaller, but sizable, gamma-gamma component in the 4(3)(+).
