Unveiling New States in <sup>98</sup>Zr: Insights from <i>β</i>-decay and <i>γ-γ</i> Angular-Correlation Studies
The nuclear structure of the 98 Zr nucleus was studied through the β − decay of 98 Y 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 of 98 Zr were identified, including the 0 + 5 and 0 + 6 levels 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 pure E 2 character of the 2 + 2 → 2 + 1 367.8-keV transition was confirmed.
