Systematics of the mean energy and the mean multiplicity of prompt neutrons originating from [sup.232]Th fission

Systematics of the mean energy and the mean multiplicity of prompt neutrons originating from [sup.232]Th fission

The cross section for the neutron-induced fission of [sup.232]Th target nuclei, [σ.sub.f]([E.sub.n]), was described within statistical theory. The spectra of the mean multiplicity, [bar.v]([E.sub.n]), and the mean energy, [bar.E]([E.sub.n]), of secondary neutrons accompanying [sup.232]Th fission ind...

Beschreibung
Zusammenfassung:The cross section for the neutron-induced fission of [sup.232]Th target nuclei, [σ.sub.f]([E.sub.n]), was described within statistical theory. The spectra of the mean multiplicity, [bar.v]([E.sub.n]), and the mean energy, [bar.E]([E.sub.n]), of secondary neutrons accompanying [sup.232]Th fission induced by neutrons of energy extending up to [E.sub.n] = 20 MeV were analyzed on the basis of the chance structure of the cross section.
