Further study on parameterization of reactor NAA: Pt. 4

This paper, the fourth in a series, describes the parametric corrections for summing effects caused by cascade-crossover transitions. The definition of 'total response of Ge detector for a single energy γ-ray' has for the first time been clarified with scattering γ contributions at low energy regions included. Peak to total ratio (P/T) has been proven to be dependent of counting geometry and measurement surroundings. This P/T definition has been verified on nuclides with typical cascade-crossover γ transition (e.g.75Se). Nuclear parameters related to summing effect corrections have been tabulated for 72 nuclides of NAA interest
