Abstract

The half-lives of three β-decaying states of In8249131 have been measured with the GRIFFIN γ-ray spectrometer at the TRIUMF-ISAC facility to be T1/2(1/2-)=328(15)ms, T1/2(9/2+)=265(8)ms, and T1/2(21/2+)=323(55)ms, respectively. The first observation of γ rays following the βn decay of In131 into Sn130 is reported. The β-delayed neutron emission probability is determined to be P1n=12(7)% for the 21/2+ state and 2.3(3)% from the combined 1/2- and 9/2+ states of In8249131 observed in this experiment. A significant expansion of the decay scheme of In131, including 17 new excited states and 35 new γ-ray transitions in Sn8150131 is also reported. This leads to large changes in the deduced β-branching ratios to some of the low-lying states of Sn131 compared to previous work with implications for the strength of the first-forbidden β transitions in the vicinity of doubly magic Sn8250132.
