| 英文摘要 | The Viola-Seaborg formula is a well-known formula for alpha decay half-life of heavy nuclei. In this work we obtain a set of new parameters for this formula through a least-square fit to even-even nuclei between Z = 84 and Z = 110 with N greater than 126. On average, the formula can reproduce the half-lives of heavy even-even nuclei with a factor of 1.3. In order to improve the calculated results for odd-A nuclei and for odd-odd nuclei, we obtain a generalized form of the Viola-Seaborg formula by including the influence of orbital angular momentum of a particle on half-lives of odd-A nuclei and odd-odd nuclei. On average, half-lives of odd-A and odd-odd nuclei can be reproduced with a factor of 2.5 by the generalized Viola-Seaborg formula. |
