Test version EMPIRE-2.19beta (Lodi^*)
March, 2005

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)
