Systematic Calculation on Ground State Properties of Even-even Superheavy Nuclei with Relativistic Mean-field Theroy

摘要: 在形变的相对论平均场模型下采用NL Z2,TMA两套参数对一些偶 偶核基态性质进行了系统的计算,并将理论计算的结合能、α衰变能与已知的实验数据进行了对比分析.结果发现两方面的数据能够比较好地吻合,从而验证了相对论平均场模型对超重核研究是可行的.同时在计算中给出了未知核素基态性质的计算结果,可供以后在理论或实验上研究超重核时参考. The ground state properties of the eveneven nuclei with proton number Z=94-104 have been systematically calculated in the deformed relativistic meanfield (RMF) theory with two sets of force parameters, TMA and NL Z2. Comparing the calculated binding energies and alphadecay energys with the experimental ones, it is found that theoretical results are in good agreement with experimental data. The reliability of the RMF model for eveneven superheavy nuclei has been tested by this comparison...Abstract: The ground state properties of the eveneven nuclei with proton number Z=94-104 have been systematically calculated in the deformed relativistic meanfield (RMF) theory with two sets of force parameters, TMA and NL Z2.
