文摘

Neutron resonance structures of nuclides have been studied over a wide energy range as these parameters are used for regulating the inputs to optical and statistical model calculations. On the basis of high resolution data on resonance parameters (E0E0, ΓnΓn, JπJπ), s-wave neutron strength functions (S0S0) for individual JπJπ values are calculated and the J-dependence of it has been investigated for 79 odd nuclides. Our analysis of statistical properties shows the J-dependence of (S0S0) and this contribution should be included in the OM calculations. Our study well materializes the presence of intermediate structure (IS) for 24 odd nuclides within both data and information reported in literature.
