利用提出的远离稳定线附近的原子核β-衰变寿命的指数规律理论计算公式,对N=82附近快中子过程中等待点核素的β-衰变寿命进行了理论计算,比较了所获得的计算结果与最新的理论结果和实验结果并加以讨论.研究表明,相对于理论复杂和计算时间长的微观理论计算而言,利用考虑壳效应的远离稳定线的原子核β-衰变寿命指数规律理论计算公式能较快且准确地得出快中子俘获过程(R过程)等待点核素的β-衰变寿命.这能为R过程核素合成网络计算研究提供有效可靠的重要物理输入,并对今后天体中核素的合成研究具有重要意义.
Using the theoretical formula of exponential law for the β-decay lifetime of the nucleus away from the stable line, the β-decay lifetime of the radionuclide waits in the vicinity of N = 82 is theoretically calculated, and the calculated results are compared The results are compared with the latest theoretical results and experimental results.The results show that compared with the theoretic calculation of microscopic theoretical calculation and long time-theoretic calculations, the theoretical calculation formula of β-decay life-span index Can quickly and accurately obtain the β-decay life expectancy of the radionuclide wavering in the fast neutron capture process (R process), which can provide an effective and reliable important physical input for the computational study of the radionuclide synthesis network in the R process, The synthesis of nuclides is of great significance.
