TALYS is software for the simulation of nuclear reactions. Many state-of-the-art nuclear models are included to cover all main reaction mechanisms encountered in light particle-induced nuclear reactions. TALYS provides a complete description of all reaction channels and observables. It is a versatile tool to analyse basic microscopic experiments and to generate nuclear data for applications.
Specific features of the TALYS package :
an exact implementation of many of the latest nuclear models for direct, compound, pre-equilibrium and fission reactions.
a continuous, smooth description of reaction mechanisms over a wide energy range (0.001- 200 MeV) and mass number range (12 < A < 339).
completely integrated optical model and coupled-channels calculations by the ECIS-06 code
incorporation of recent optical model parameterisations for many nuclei, both phenomenological (optionally including dispersion relations) and microscopical.
total and partial cross sections, energy spectra, angular distributions, double-differential spectra and recoils.
discrete and continuum photon production cross sections.
excitation functions for residual nuclide production, including isomeric cross sections.
exact modeling of exclusive channel cross sections, e.g. (n; 2np), spectra, and recoils.
automatic reference to nuclear structure parameters as masses, discrete levels, resonances, level density parameters, deformation parameters, fission barrier and gamma-ray parameters, generally from the IAEA Reference Input Parameter Library
various width fluctuation models for binary compound reactions and, at higher energies, multiple Hauser-Feshbach emission until all reaction channels are closed.
various phenomenological and microscopic level density models.
various fission models to predict cross sections and fission fragment and product yields.
models for pre-equilibrium reactions, and multiple pre-equilibrium reactions up to any order.
astrophysical reaction rates using Maxwellian averaging.
option to start with an excitation energy distribution instead of a projectile-target combination.
use of systematics if an adequate theory for a particular reaction mechanism is not yet available or implemented, or simply as a predictive alternative for more physical nuclear models.

Can be installed under linux, unix, and windows.
The author tested TALYS only on Linux systems, but it is likely that it will also run under Windows with minor modifications (e.g. machine.f).
