本文研究了β衰变全吸收谱的分析方法，以获得β强度分布。利用原子核布居和衰变的统计模型，研究了子核能级电磁退激发中未知分支比对最终结果的影响。总衰减强度似乎是相当不敏感的假设上的分支比和系统的不确定性的强度分布的形状进行量化。
The method of analysis of β-decay total absorption spectra in order to obtain β-strength distributions is studied. The influence on the final result of unknown branching ratios in the electromagnetic de-excitation of levels in the daughter nucleus is investigated with the help of the statistical model of the population and decay of the nucleus. The total decay strength appears to be rather insensitive to assumptions on the branching ratios and the systematic uncertainty on the shape of the strength distribution is quantified.
