| Abstract: |
A systematic analysis of α -decay half-lives of radioactive lanthanide isotopes, T 1 ∕ 2 α , has been developed which allows one to obtain an accurate and reliable T 1 ∕ 2 α -value of (1 0 3. 4 ± 5. 3) Ma for the extinct 1 4 6 Sm isotope, and to predict a T 1 ∕ 2 α -value of (1. 8 ± 0. 2) × 1 0 1 8 a for the yet unknown alpha radioactivity of 1 4 9 Sm isotope.
