γ softness

Sažetak
Lifetimes of the 2+ 1 , 4+ 1 , 6+ 1 , 2+ γ , and 3+ γ states in 104, 106Ru were measured by using the recoil-distance Dopplershift technique and the Cologne Plunger device. Low-lying excited states in both nuclei were populated in a 104Ru(18O, 18O) 104Ru* inelastic scattering and in a 104Ru(18O, 16O) 106Ru two-neutron transfer reaction using the Cologne FN Tandem accelerator. The experimental energy levels and deduced electromagnetic transition probabilities are compared in the context of γ softness and the mapped interacting boson model with input from the microscopic self- consistent mean-field calculation using a Gogny interaction. The newly obtained results for the γ band give a more detailed insight about the triaxial behavior of 104, 106Ru. The results will be discussed in the context of γ soft and rigid triaxial behavior which is present in the neutron- rich Ru isotopes.
