Abstract
En 中文
In this Brief Report we extend the alpha-decay half-life calculation to the superheavy emitter region to verify whether these nuclei satisfy the recently observed systematics [D. N. Poenaru et al., Phys. Rev. C 83, 014601 (2011); C. Qi et al., Phys. Rev. C 80, 044326 (2009)]. To establish the systematics, we have used the a-cluster potential description, which was originally developed to study alpha decay in connection with nuclear energy level structure [B. Buck et al., Phys. Rev. C 51, 559 (1995)]. The quantum-mechanical tunneling calculation has been employed to obtain the half-lives, showing that with this treatment the systematics are well reproduced in the region of heavy nuclei. Finally, the half-life calculation has been extended to the superheavy emitters to verify whether the systematics can still be observed.
