A high-statistics $\beta $-decay experiment was conducted at the TRIUMF-ISAC facility using the $8\pi $ $\gamma $-ray spectrometer and its ancillary detectors to study the low-spin structure of $^{98}$Zr. The analysis of $\gamma $–$\gamma $ and $e^-$–$\gamma $ coincidence data is presented. New measurements of $\gamma $-ray branching ratios and mixing ratios are reported for four $J^{\pi } = 2^+$ states located above 2 MeV excitation energy in $^{98}$Zr. Based on these measurements, ratios of $B$(E2) values for transitions to lower-lying levels are determined, highlighting the preferential decay paths of these $2^+$ states.

Unveiling New States in ⁹⁸ Zr: Insights from β -decay and γ-γ Angular-Correlation Studies

https://doi.org/10.1051/epjconf/202532901012

The nuclear structure of the⁹⁸Zr nucleus was studied through theβ⁻decay of⁹⁸Y_g.s.at the TRIUMF-ISAC facility. The use of the 8π γ-ray spectrometer with its ancillary detectors SCEPTAR and PACES enabled γ-γ and γ-e⁻coincidence measurements as well as γ-γ angular correlations. The level spin assignments and transition mixing ratios obtained in this study were in good agreement with previous results. Furthermore, 12 previously unknown states in the low-energy region of⁹⁸Zr were identified, including the 0⁺₅and 0⁺₆levels at 2418 and 2749 keV, respectively. The 2⁺and I=1 natures for multiple newly observed and previously known (but not firmly assigned) states have been established. Additionally, the previously assumed pureE2 character of the 2⁺₂→ 2⁺₁367.8-keV transition was confirmed.
