Dipole excitations in Ru-96

Candidates for the two-phonon quadrupole-octupole 1⁻ state and the two-phonon mixed-symmetry 1⁺_ms state have been identified in the N=52 isotope 96Ru using the nuclear resonance fluorescence technique at the bremsstrahlung facility of the Stuttgart Dynamitron accelerator. Detailed information on energies, spins, branching ratios, and transition strengths of four new dipole excitations in 96Ru have been obtained. The observed dipole excitations are nearly at the same energies as in 94Mo, and the transition probabilities are comparable to those for the decay of the (2+1⊗3−1)1−and the (2+1⊗2+ms)1+ms states in 94Mo.
