【摘要】 超铀元素结构和性质的研究对于超重核实验的合成具有重要的意义,本文简要介绍了远离β稳定线原子核β-衰变寿命的指数规律和理论计算公式.利用该公式对超铀区原子核β-衰变寿命进行了系统的理论计算和讨论.计算结果与实验数据和宏观-微观模型结果的比较表明:该指数计算公式对超铀附近原子核寿命的计算结果与实验数据符合较好,也与宏观-微观的结果符合较好.对这些同位素链上原子核的未知β-衰变寿命的进行了理论预言,可为将来的实验提供理论参考.更多还原

【Abstract】 Studies on nuclear structure of transuranic elements are very important in synthesizing new superheavy elements.The exponential law between β--decay half-lives and the nucleon number(Z,N) of parent nuclei is shortly reviewed.Using the formula with four parameters,the β--decay lives of transuranic nuclei far from stable line are systematically calculated and compared with experimental data.It is shown that the calculated results are in good agreement with the experimental data and the Mller calculation results.The unknown β--decay lives of transuranic nuclei are predicted,which can provide references for future experimental research on transuranic and superheavy elements.更多还原
