Element stability profileEdit

The stability profile of the OE isotopes of 35Br Bromine is irregular due to the low reported half-life of the OE isotope OE35Br78, which is only 6.45 minutes (log second half-life value = 2.59. This value is below the values of the adjacent OE isotopes OE35Br76, at 16 hours, (log-second value = 4.760 and of OE35Br80 at 4.2 hours (log-second value = 4.20. There is obviously an irregularity in the OE35Br78 and also possibly the OE35Br80 half-life values.WFPM (talk) 18:15, 17 April 2013 (UTC)
