翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Isotopes of dysprosium ： ウィキペディア英語版 Isotopes of dysprosium Naturally occurring dysprosium (Dy) is composed of 7 stable isotopes, 156Dy, 158Dy, 160Dy, 161Dy, 162Dy, 163Dy and 164Dy, with 164Dy being the most abundant (28.18% natural abundance). Twenty-nine radioisotopes have been characterized, with the most stable being 154Dy with a half-life of 3.0 million years, 159Dy with a half-life of 144.4 days, and 166Dy with a half-life of 81.6 hours. All of the remaining radioactive isotopes have half-lives that are less than 10 hours, and the majority of these have half-lives that are less than 30 seconds. This element also has 12 meta states, with the most stable being 165mDy (t1/2 1.257 minutes), 147mDy (t1/2 55.7 seconds) and 145mDy (t1/2 13.6 seconds). The primary decay mode before the most abundant stable isotope, 164Dy, is electron capture, and the primary mode after is beta decay. The primary decay products before 164Dy are terbium isotopes, and the primary products after are holmium isotopes.
