摘要 运用变形的相对论平均场理论系统地探讨了新核素265Bh及其α衰变链的基态性质.对关联的处理采用了BCS方法,不成对核子的处理运用了“阻塞”法后,所计算的结合能和四极形变符合了有限力程小液滴模型的结果,计算表明研究的α衰变链具有中等大小的长椭球形变;且计算的α衰变能Qα成功地与实验符合.在此基础上进一步研究了新核素265Bh的单粒子能级. The properties of the nuclei belonging to the newly discovered alpha-decay chain starting from ^265Bh have been studied. The axially deformed relativistic mean field (RMF) calculation with the force TMA and NL-Z2 has been performed in the blocked BCS approximation. Some ground state properties such as the binding energies, deformations, spins and parities, as well as Q-values of the alpha decay for this decay chain have been calculated and compared with known experimental data. Good agreement is observed. The single-particle spectrum of the nucleus ^265Bh has been studied.
