Evaluated cross section libraries and kerma factors for neutrons up to 100 MeV on {sup 40}Ca and {sup 31}P

PDF Version Also Available for Download.

Description

The authors present evaluations of the interaction of 20 to 100 MeV neutrons with calcium and phosphorus, which follows on from the previous work on carbon, nitrogen, and oxygen. The aim is to accurately represent integrated cross sections, inclusive emission spectra, and kerma factors, in a data library which can be used in radiation transport calculations. They apply the GNASH nuclear model code, which includes Hauser-Feshbach, preequilibrium, and direct reaction mechanisms, and use experimental measurements to optimize the calculations. Total, elastic, and nonelastic cross sections, angle-energy correlated emission spectra for light ejectiles with A {le} 4 and gamma-rays, and average ... continued below

Total, elastic, and nonelastic cross sections, angle-energy correlated emission spectra for light ejectiles with A {le} 4 and gamma-rays, and average energy depositions, are determined. The expected accuracy of the calculated cross sections and kerma factors is discussed.
