Kinetic Energy Spectra of Foil-Transmitted Fission Fragments of 252Cf

Lynn B. Bridwell, Shawn Bucy

Open publisher page 2 citations

Abstract

A mathematical model for the calculation of kinetic-energy spectra of fragments from the spontaneous fission of 252Cf has been developed. This model predicts the spectra of these fragments after transmission through any absorber whose thickness and composition are known. The model may be applied to other fissioning elements with minor modifications. Agreement between calculated and experimentally observed peak positions agree to within 5%. The energy shifts due to an absorber may be calculated to within 25% for the thicknesses of foils used.
