摘要
介绍了远离稳定线原子核β-衰变寿命与母核核子数之间的指数规律和理论计算公式,具体对Z=40～43同位素链上原子核的β-衰变寿命进行了计算,并将计算结果与实验数据和宏观微观模型的结果进行了比较.发现计算结果与实验数据符合较好,也与其他模型符合较好.此外还对这些同位素链上原子核的未知β-衰变寿命进行了理论预言.
The exponential law between β- decay half-life and the nucleon number （Z,N） of parent nuclei and a new formula using to calculate theβ- -decay lives of nuclei far from stable line are shortly introduced. With this formula, theβ- -decay half life of isotopes Z=40--43 are calculated. The results are compared with experimental data and other theoretical results and good agreement between these data are found. The unknown β- decay lives of nuclei in these isotopes are predicted for future experimental research.
