The charged particle-induced reactions have prime importance in understanding the reaction mechanism which can be applicable to understand the particles resulting from the reaction. Nuclear reactions occur as a result of the interaction between incident particles with the target nuclei. It is important to examine the effects of the nuclear reaction, which is used as a building material in nuclear reactors. ![]() Future extensions of the system are outlined, including neutron resonance module as well as capabilities of generating covariances, using both KALMAN and Monte-Carlo methods, that are still being advanced and refined. Selected applications of EMPIRE are discussed, the most important being an extensive use of the code in evaluations of neutron reactions for the new US library ENDF/B-VII.0. This paper describes the capabilities of the code, outlines physical models and indicates parameter libraries used by EMPIRE to predict reaction cross sections and spectra, mainly for nucleon-induced reactions. The graphic user interface, written in Tcl/Tk, provides for easy operation of the system. Publication quality graphs can be obtained using the powerful and flexible plotting package ZVView. The package contains the full EXFOR (CSISRS) library of experimental reaction data that are automatically retrieved during the calculations. The results can be converted into ENDF-6 formatted files using the accompanying code EMPEND and completed with neutron resonances extracted from the existing evaluations. A comprehensive library of input parameters covers nuclear masses, optical model parameters, ground state deformations, discrete levels and decay schemes, level densities, fission barriers, moments of inertia and γ-ray strength functions. Several options for nuclear level densities include the EMPIRE-specific approach, which accounts for the effects of the dynamic deformation of a fast rotating nucleus, the classical Gilbert-Cameron approach and pre-calculated tables obtained with a microscopic model based on HFB single-particle level schemes with collective enhancement. The fission probability is derived in the WKB approximation within the optical model of fission. Advanced treatment of the fission channel takes into account transmission through a multiple-humped fission barrier with absorption in the wells. Finally, the compound nucleus decay is described by the full featured Hauser-Feshbach model with γ-cascade and width-fluctuations. The pre-equilibrium mechanism can be treated by a deformation dependent multi-step direct (ORION + TRISTAN) model, by a NVWY multi-step compound one or by either a pre-equilibrium exciton model with cluster emission (PCROSS) or by another with full angular momentum coupling (DEGAS). ![]() ![]() Direct reactions are described by a generalized optical model (ECIS03) or by the simplified coupled-channels approach (CCFUS). The code accounts for the major nuclear reaction mechanisms, including direct, pre-equilibrium and compound nucleus ones. The energy range extends from the beginning of the unresolved resonance region for neutron-induced reactions (∽ keV) and goes up to several hundred MeV for heavy-ion induced reactions. A projectile can be a neutron, proton, any ion (including heavy-ions) or a photon.
