Time response and its impact on prompt fission γ-ray spectra characteristics
The time dependence of prompt γ-ray spectral characteristics, in particular the multiplicity, was studied during the first 10 ns after the spontaneous fission of 252Cf. 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.
