Some Highlights in the Evaluations of the Thermal Cross Sections and Resonance Parameters of the Actinides

摘要

The resonance parameters and thermal cross sections of exp 235 exp 238 U and exp 239 exp 240 exp 241 exp 242 Pu are reevaluated by considering the measurements carried out since 1973. Capture, scattering, fission cross sections as well as resonance integrals are calculated from the parameters and are compared with experimental values with the objective of achieving consistency between calculations and measurements. The Dyson-Metha delta sub 3 statistical analysis was applied in order to calculate average level spacings. Calculations of average radiative widths based on systematics are carried out and are compared with experimental values as well as with Moore's and Lynn's estimates. (ERA citation 07:016713)
