Calculation of Stellar-averaged neutron capture cross sections directly from evaluated nuclear data file
- Oak Ridge National Laboratory, TN (United States); and others
Stellar (n,{gamma}) reaction rates (Maxwell-Boltzmann thermally-averaged cross sections) for elements {sup 54}Fe through {sup 209}Bi have been calculated with the resonance analysis program SAMMY, using resonance parameters from the Evaluated Nuclear Data File to generate the pointwise unaveraged cross sections as a function of neutron energy. The Evaluated Nuclear Data File includes accepted sets of resonance parameters for neutron-induced reactions over a wide mass range of nuclei. Corrections were included to provide cross section values for energies outside the range of validity of the resonance parameter description. Plots of stellar (n,{gamma}) reaction rates as a function of temperature from kT = 5 to 100 keV will be presented for many of the nuclei important to astrophysics, and, where possible, comparisons will be made with previously published values.
