3. NATURE OF PHYSICAL PROBLEM SOLVED

Calculation of fast neutron radiative capture cross section of fission products.

[ top ]

4. METHOD OF SOLUTION

Based on the Hauser-Feshbach theory. Includes corrections for n-2gamma, direct, and collective capture but does not include width fluctuation corrections.
Transmission coefficients may be read from cards, or the program will calculate them from either a black-nucleus model or from an internal optical model-program which uses various forms for a spherically symmetric potential.
Includes the effect of inelastic scattering to both known and unknown levels in the target nucleus.
