ハフニウムの同位体
1. Isotopes of hafniumNatural hafnium (Hf) consists of five stable isotopes (Hf, Hf, Hf, Hf, and Hf) and one very long-lived radioisotope, Hf, with a half-life of 2×10 years. In addition, there are 30 other known radionuclides, the most stable of which is Hf with a half-life of 8.9×10 years. No other radioisotope has a half-life over 1.87 days. Most isotopes have half-lives under 1 minute. There are also 27 known nuclear isomers, the most stable of which is Hf with a half-life of 31 years.
