摘要:

本文采用含时生成坐标方法和高斯重叠近似(TDGCM+GOA)描述了$^{252}$ Cf的裂变。我们进行分析的裂变从初始状态奠定的能量范围内从基态的状态位于4 MeV以上的裂变势垒。计算了不同宇称、能级和混合态类型下的裂变碎片质量分布,并与实验数据进行了比较。研究了波包传播总时间对最终结果的影响。所获得的质量产量的初始条件的弱依赖性。

英文摘要:

The time-dependent generator coordinate method with the gaussian overlap approximation (TDGCM+GOA) formalism is applied to describe the fission of $^{252}$Cf. We perform analysis of fission from the initial states laying in the energetic range from the ground state to the state located 4 MeV above the fission barrier. The fission fragment mass distributions, obtained for different parity, energy of levels and types of mixed states, are calculated and compared with experimental data. The impact of the total time of wave packet propagation on the final results is studied as well. The weak dependence of obtained mass yields on the initial conditions is shown.
