Stability Isotope Explanation

• Mass is represented by the atomic mass unit (AMU), where neutral carbon is defined as 12. Refer to "G. Audi and A. H. Wapstra, Nuclear Physics A565 (1993) 1" for details.
  (質量は、中性¹²C原子の質量を12とする原子質量単位で表したもので、G. Audi and A. H. Wapstra, Nuclear Physics A565 (1993) 1によります)
• Isotopic abundance is taken from "J. R. De Laeter et al., Pure and Applied Chemistry 75 (2003) 683".
  (同位体存在度は、J. R. De Laeter et al., Pure and Applied Chemistry 75 (2003) 683によります)
• Parenthesized numbers are errors, and correspond to the lowest digits of the abundance.
  (括弧内の数字は誤差で、存在度の値の末尾の数値に対応します)
