Collectivity of the deformed structure in 96Zr from complementary Coulomb-excitation and β-decay measurements. Physics Letters B, p.140481.https://doi.org/10.1016/j.physletb.2026.140481https://hdl.handle.net/10566/24684The 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.enElectromagnetic propertiesQuadrupole deformationShape coexistenceCoulomb-excitation measurementComplementary β -decayArticle
