Examples of different types of neutron spectra used in an effective cross-section processing system to determine multi-group effective cross-sections
Some spectra depend on parameters that can be set by the user of the cross-section processing codes. In the following, parameters and their default values are indicated; energies are expressed in electron volts (eV). Spectra are not necessarily normalized to unity: the spectra normalization constant is simplified when constructing the multi-group cross-section.
1. Maxwell spectrum
The Maxwell spectrum is defined by :
