Resumen

The ¹¹⁶Sn nucleus was studied via the β^- decay of ¹¹⁶In utilizing the 8 π spectrometer and its auxiliary detectors at TRIUMF-ISAC. The resulting K-shell conversion coefficients, K/L ratios, and multipole mixing ratios are presented. The 23+→21+931 keV and 22+→21+819 keV transition mixing ratios were re-measured and found to be δ=+1.8-0.5+0.7 and - 1. 83 (8) , respectively. Newly measured mixing ratios for transitions among the low-lying I^π= 4 ⁺ states in ¹¹⁶Sn, when combined with γ-ray intensity data, suggest that the 2529 keV 42+ state possesses a neutron broken-pair admixture in addition to its dominant proton 2p-2h component.
