The time dependence of prompt \(\gamma \)-ray spectral characteristics, in particular the multiplicity, was studied during the first 10 ns after the spontaneous fission of \({}^{252}\)Cf. The impact of prompt window and experimental time resolution on the determination of prompt multiplicities is assessed and described mathematically. As a consequence we are able to offer corrections that allow a reliable comparison of results from different measurements. An apparent discrepancy between a theoretical and an experimentally found time dependence is explained by the influence of a finite experimental timing resolution as well as the choice of the prompt timing window.

时间响应及其对快速裂变$$ \γ$$γ射线光谱特性的影响

瞬变\（{γ ^ \ 252}） Cf自发裂变后的最初10 ns内，研究了瞬变\（\γ\）射线光谱特性的时间依赖性。快速评估窗口和实验时间分辨率对确定快速多重性的影响，并进行数学描述。因此，我们能够提供校正，从而可以可靠地比较不同测量结果。理论上和实验上发现的时间依赖性之间的明显差异是由有限的实验时间分辨率的影响以及快速时间窗口的选择所造成的。
