The resulting $Q_{2{\beta }^{+}}$ and mass-excess values of $_{}^{84}\text{Sr}$ determined in this work based on the weighted mean of the cyclotron frequency ratio $\overline{R}$. The frequency ratio $\overline{R}$, $Q_{2{\beta }^{+}}$ values (in keV), and the mass excess (ME, in keV/${\text{c}}^2$) of the parent, as determined in this work, are provided alongside the corresponding values from AME2020 [28] for comparison
