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 the superheavy nucleus ~ (294) 118 and its α decay chain are studied by using the theory of deformation-dependent relativistic mean fields. The binding energies and α decay energies per nucleon and the ground state deformations of these nuclei are given and compared with the experimental results It is found that the theoretical calculation and experimental results are in good agreement, which shows that the theory of relativistic mean field is reasonable and valid for the description of the ground state properties of overweight nuclei.
