超重核^(294)118及其α衰变链的基态性质

Ground-State Properties of Superheavy Nuclide ^(294)118 and It'sα-Decay Chain

用形变约束的相对论平均场理论系统研究了超重核^(294)118及其α衰变链的基态性质,给出了这些原子核的每核子结合能和α衰变能以及基态形变,并与实验结果进行了比较,发现理论计算和实验结果符合得很好,表明相对论平均场理论对超重核基态性质的描述是合理有效的.

The ground-state properties of superheavy nuclide ^294118 and it＇s co-decay daughters are investigated in the deformed relativistic mean field （RMF） theory with the TMA effective interaction, where the pairing correlations are treated with the usual BCS approximation. Binding energies per nucleon, alpha decay energies and deformations are calculated and compared with the known experimental data. A good agreement between the calculated result and the data is obtained. This shows the validity of RMF theory in studying the ground state properties of super heavy nuclei.
