The references of group "lower-alpha":
  1. ↑ The most stable isotope of seaborgium cannot be determined based on existing data due to uncertainty that arises from the low number of measurements. The half-life of 267Sg corresponding to one standard deviation is, based on existing data, 9.8+11.3
    −4.5     minutes,[1] whereas that of 269Sg is 5±2 minutes;[2] these measurements have overlapping confidence intervals.
