Codebase for the Bay Area Nuclear Data Group

Welcome to the central codebase for the Bay Area Nuclear Data Group! As part of the research that our group carries out, we have developed a number of software packages, data processing and analysis tools, and other useful tools for scientific computation. This website serves to collect our public codebase in one location, provide distribution information, and document the use and utility of this codebase. Links for the various projects will follow, along with contact information and documentation.

Happy Computing!!!


Curie is a python toolkit to aid in the analysis of experimental nuclear data, particularly for datasets related to isotope production and . Its name is inspired by Marie Curie, who developed the theory of radioactivity. The primary application for Curie is (gamma-ray) activation analysis, with specific utilities developed for the charged-particle stacked-target activation technique. Curie also comes with access to a number of nuclear structure, and nuclear reactions databases. It also has methods for accessing atomic properties, such as attenuation coefficients and charged particle stopping powers. More information, documentation on the full API, and a distribution may be found here.


The Fission Induced Electromagnetic Response (FIER) code has been developed to analytically predict delayed gamma-ray spectra following fission. 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.
