Microscopic models for nuclear reaction rates

Journal of Physics G: Nuclear and Particle Physics, 1993
Reports on a microscopic description of low-energy nuclear reactions, in the framework of the generator coordinate method. The model is briefly presented and illustrated by applications to the 7Li(n, gamma )8Li, 7Be(p, gamma )8B, and 12C( alpha , gamma )16O capture reactions and to the 8Li( alpha ,n)11B transfer reaction.

Lattice models for quark, nuclear structure and nuclear reaction studies

Journal of Physics G: Nuclear and Particle Physics, 1997
Because of their computational simplicity, lattice models have found various uses in quark, nuclear structure and nuclear reaction (multifragmentation and heavy-ion) studies. However, differences in the mean density of particles among crystal types lead to significantly different properties, indicating that simulations using nucleon lattices should ...

Global Microscopic Models for Nuclear Reaction Calculations

AIP Conference Proceedings, 2005
Important effort has been devoted in the last decades to measuring reaction cross sections. Despite such effort, many nuclear applications still require the use of theoretical predictions to estimate experimentally unknown cross sections. Most of the nuclear ingredients in the calculations of reaction cross sections need to be extrapolated in an energy

Overview of nuclear reaction models used in nuclear data evaluation

Radiochimica Acta, 2001
A brief outline of nuclear reaction mechanisms including the optical model, the Distorted Wave Born Approximation, the Coupled Channels, classical and quantum-mechanical preequilibrium models and the Compound Nucleus is given. The relations among different nuclear reaction and structure models are indicated.

Unified multifragmentation-evaporation nuclear reaction models

Physical Review C, 1991
A simple and exactly solvable unified model for fragmentation was recently proposed. It involved a single parameter which served to tune relative contributions of evaporation and multifragmentation to the mass-yield distribution for nuclear reactions.

Model for Nuclear Reactions with Neutrons

Physical Review, 1954
A simple model is proposed for the description of the scattering and the compound nucleus formation by nucleons impinging upon complex nuclei. It is shown that, by making appropriate averages over resonances, an average problem can be defined which is referred to as the "gross-structure" problem.

Nuclear Reactions (Optical Model. Deuteron Reactions)

1959
In this lecture we shall consider nuclear reactions from an entirely different point of view. To eliminate the complications which arise because of the Coulomb field of the nucleus we shall consider only neutron reactions.

Cascade-exciton model of nuclear reactions

Nuclear Physics A, 1983
Abstract An approach combining essential features of the exciton and intranuclear cascade models is developed. The cascade-exciton model predictions for the energy spectra, angular distributions and double differential cross sections of nucleons and complex particles as well as for the excitation functions are analyzed at incident nucleon energies T

Modeling Compound Nuclear Reactions with EMPIRE

2020
EMPIRE by Herman et al. (Nucl Data Sheets 108:2655, 2007) is a modular system of nuclear reaction codes, comprising various nuclear models, and designed for calculations over a broad range of energies and incident particles. A projectile can be a neutron, a proton, an ion, or a photon.
