摘要: A method has been developed for evaluation of neutron capture γ-ray spectrum. It couples measured intensities primary and secondary discrete—-ray with a cascade model to calculate the unresolved part spectrum, adds discrete obtain whole The uses level density formula proposed by Gilbert & Cameron Brink Axel form El profile function modification. This was applied thermal spectra in six hafnium isotopes 181Ta extended also non-thermal 0.25 0.5 MeV neutrons empirical assumptions. calculated results were compared experiments agreement good not only terms gross structure, but fine structure which appears at high low energies.
