EMPIRE-II

The Battle of Lodi (May 10, 1796) painted by Lejeune

Test version EMPIRE-2.19beta (Lodi*)
March, 2005
EXFOR library May 2007, retrieval system March 2008

Modular system of nuclear reaction codes for advanced modeling of nuclear reactions using various theoretical models. It consists of a number of FORTRAN codes, input parameter libraries, and experimental data library (EXFOR/CSISRS) - operated through the Graphic User Interface (GUI).

EMPIRE is intended to be a general, flexible, and easy to use tool for basic research and evaluation of nuclear data. It offers a possibility of combining several theoretical approaches, choosing among alternative input parameters and calculating extended set of observables in a single run. Nuclear data evaluation is facilitated by the ENDF-6 formatting, file verification and graphical comparison with experimental data.

New features in 2.19

  • Multi-modal fission with multi-hump barriers
  • Photo-nuclear reactions
  • Reactions on excited targets
  • Exact treatment of exclusive spectra
  • Improved algorithm for recoil spectra
  • Suite of gamma-ray strength functions from RIPL-2
  • Exciton model with cluster emission (Iwamoto-Harada)

* It was at the battle for the bridge of Lodi (May 10, 1796) that Napoleon Bonaparte proved himself to his men and won the nickname 'The Little Corporal'
