Low-lying collective excitations in near-spherical nuclei are usually interpreted in terms of multiphonon excitations.
Especially for the coupling of a quadrupole and an octupole phonon, one expects a high degree of harmonicity
compared to quadrupole-quadrupole and octupole-octupole couplings. In 96Ru, a candidate for the (2+⊗3−)1−
has been identified recently based on its energy [1] but experimental information of its decay properties are still sparse. Since
in an inelastic proton scattering experiment the coincident detection of the scattered proton and the deexciting γ-ray
yields additional information on the excitation energy, a 96Ru(p,p′γ) experiment has
been performed at WNSL, Yale, to investigate multiphonon excitations in 96Ru. The level scheme could be significantly extended
and new branching ratios have been determined. First experimental results will be presented and compared to the vibrational model.
