Systematic measurements of prompt fission γ rays – and what they tell us about fission fragment de-excitation

Systematic measurements of prompt fission γ rays – and what they tell us about fission fragment de-excitation

In a recent measurement of prompt γ rays from the spontaneous fission of 252Cf an experimental setup was chosen that allowed the study of angular correlations between γ rays and the nuclei from which they were emitted. The observed angular distribution of prompt fission γ rays was then analyzed to e...
