| dc.description.abstract | The B(E2;22+→01+) value in 96Zr was determined from a Coulomb-excitation measurement with 12C and 16O beams performed at the Maier-Leibnitz Laboratory with a Q3D magnetic spectrograph. High-precision γ -ray branching ratios in the decay of the 22+ state in 96Zr, and a new value of the 22+→21+ multipole mixing ratio, were obtained from a complementary β -decay experiment, performed using the GRIFFIN spectrometer at the TRIUMF-ISAC facility. Combining these results yields B(E2;22+→02+)=38.9(57) W.u. which is in agreement with the previous measurement, but considerably more precise. The observed differences between the properties of structures built on the 02+ states in 94Zr and 96Zr are discussed in the context of possible triple shape coexistence in Zr nuclei. | |
