EC decay properties of 213At somehow resemble 157Tb
Of course, considering its 125 ns half-life, observation of electron capture of 213At is infeasible (perhaps with a probability at the order of 10-15%). An upper limit of the branching ratio has not been determined, but the value is expected here to be < 2.5×10-12% (half-life > 57.87 d). 129.104.241.214 (talk) 22:24, 20 December 2023 (UTC)

Beta-decay branching ratio upper limits of 212At and 216At
See https://www.nndc.bnl.gov/ensnds/212/At/adopted.pdf and https://www.nndc.bnl.gov/ensnds/216/At/adopted.pdf. Neither beta mode for neither nuclide has been observed. 103.166.228.86 (talk) 05:28, 19 April 2024 (UTC)
