Abstract
The β decay of neutron-rich 129In into 129Sn was studied using the GRIFFIN spectrometer at the ISAC facility at TRIUMF. The study observed the half-lives of the ground state and each of the β-decaying isomers. The level scheme of 129Sn has been expanded with thirty-one new γ-ray transitions and nine new excited levels, leading to a reevaluation of the β branching ratios and level spin assignments. The observation of the β decay of the (29/2+) 1911-keV isomeric state in 129In is reported for the first time, with a branching ratio of 2.0(5)%.
