摘要
利用相对论平均场理论系统地探讨了新核素2 5 9Db及其α衰变链的性质和结构以及对关联效应与形变效应的影响 .考虑对关联影响后的变形相对论平均场理论成功再现了实验的Qα 并揭示了所研究的α衰变链具有较大的形变 .在此基础上进一步讨论了新核素2 5
The new nuclide 259 Db and its α decay chain are systematically studied in the framework of the relativistic mean field (RMF) theory with NL3 and TM1 effective interactions. The nuclide 259 Db and its α decay daughter nuclei are calculated in a RMF framework with and without the pairing correlation. With the pairing gaps obtained from the RCHB, the deformed RMF+BCS has been carried out for these nuclei. It has been found that the DRMF+BCS well reproduces the data and implies that the new nuclide 259 Db and its α decay daughter nuclei are highly deformed. The α decay energy Q α for different channel has been given and it seems that the ground state to ground state Q α values from DRMF+BCS reproduce the data well. Furthermore the single particle levels of the α decay chain are studied carefully and the explanation for the stability is also presented.
