New Software Package to Model Delayed Gamma-Ray Spectra

Posted by:

The Fission Induced Electromagnetic Response (FIER) code enables analytical prediction of delayed-ray spectra following fission. Developed by NSSC Fellow Eric Matthews with support from NSSC Executive Director Bethany Goldblum, LBNL Scientist Brian Quiter, and NSSC undergraduate Matthew Shinner, FIER uses evaluated nuclear data and solutions to the Bateman equations to calculate the time-dependent populations of fission products and their decay daughters resulting from irradiation of a fissionable isotope. These populations are then used in the calculation of gamma-ray emission rates to obtain the corresponding delayed gamma-ray spectra.
