摘要
在形变的相对论平均场模型下,采用NL-Z2,TMA两套参数对质子数为103—109的奇-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对比,发现两者符合得很好,肯定了相对论平均场模型对超重核研究的可靠性,同时对未知核素基态性质的计算结果可供未来的超重核理论和实验研究参考。
The ground state properties of the odd-even nuclei with proton number Z = 103-109 have been systematically calculated in the deformed relativistic mean-field (RMF) theory with two sets of force parameters, NL-Z2 and TMA. When comparing the calculated binding energies and alpha-decay energies with the experimental ones, we find that the theoretical results are in good agreement with the experimental data. The reliability of the RMF model for odd-even super-heavy nuclei has been tested by this comparison. The properties of some unknown nuclei are predicted and they will be useful for future theoretical and experimental researches of superheavy nuclei.
