Experimental data on inelastic neutron scattering are analyzed in a Hauser-Feshbach-Moldauer approach with a coupled-channel estimates of the direct reaction contribution. For the direct excitation of the ground state rotational band levels with Jπ = 0+, 2+, 4+, 6+, 8+ the rigid rotator model was used, whereas for the direct excitation of members of the β-, γ- (Kπ = 02+, 03+, 2+) and first octupole band (Kπ = 0-) a soft-deformable rotator model was used. Quadrupole, octupole, hexadecapole and gamma-deformation parameters are defined by consistent analysis of excited rotational-vibrational band structures and excitation cross sections of the relevant levels. Structures evident in measured neutron emission spectra for En ∼ 1-6 MeV are correlated with excitation of levels of Kπ = 0- and Kπ = 02+, 03+, 2+ bands.
