Propriétés statistiques de l'interaction des neutrons de résonance avec les noyaux moyens et lourds. - IV. Etude des largeurs de radiation

Abstract

Relative measurement of the ratio Γ γ/ Γ is made from resonance to resonance with a large liquid scintillator. Results are given for Nd and Pt. Occurrence of fluctuations of the Γ γ values is discussed. The annular crystal spectrometer is used to investigate the possible contribution from direct radiative capture in Au.
