Abstract.

The 116Sn nucleus was studied via the \(\beta^{-}\) decay of 116In utilizing the \(8\pi\) spectrometer and its auxiliary detectors at TRIUMF-ISAC. The resulting K-shell conversion coefficients, K/L ratios, and multipole mixing ratios are presented. The \(2_{3}^{+} \rightarrow 2_{1}^{+} 931\) keV and \( 2_{2}^{+} \rightarrow 2_{1}^{+} 819\) keV transition mixing ratios were re-measured and found to be \( \delta = +1.8_{-0.5}^{+0.7}\) and \( -1.83(8)\), respectively. Newly measured mixing ratios for transitions among the low-lying \( I^{\pi} = 4^{+}\) states in 116Sn, when combined with \(\gamma\)-ray intensity data, suggest that the 2529 keV \(4_{2}^{+}\) state possesses a neutron broken-pair admixture in addition to its dominant proton 2p-2h component.
