The level structure and the decay properties of levels in Ru96 up to 3.3 MeV of excitation have been investigated via singles directional-correlation and Doppler-shift measurements following the Ru96(p,p) reaction at 7.0 MeV proton energy. The level and decay scheme of Ru96 was supplemented and clarified on the basis of -coincidence measurements. The directional correlations for many transitions provided (i) reliable branching ratios, (ii) J assignments, and (iii) multipole mixing ratios (E2/M1) from analysis of the correlations via the compound statistical theory for nuclear reactions. In many cases the measured cross sections helped for a more precise assignment of J values. Lifetimes for four states and limits to three additional states were obtained by the Doppler-shift attenuation method from singles spectra, taken in the presence of standards, at eight angles between 0°and 110°to the beam direction. For several transitions in Ru96 values or limits of B(E1), B(E2), and B(M1) were obtained. The levels of Ru96 and their decay properties were calculated in the shell-model framework and are compared with the corresponding experimental quantities. © 1986 The American Physical Society. |
