Unified multifragmentation-evaporation nuclear reaction models
Physical Review C, 1991A 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.

Resonance reactions and the nuclear shell model I
Annals of Physics, 1964Abstract H. Feshbach's unified theory of nuclear reactions has been applied to the calculation of elastic neutron scattering from a N15 target. The target nucleus is considered to be adequately described as a p 1 2 hole configuration relative to the O16 core.

Nuclear Reactions (Optical Model. Deuteron Reactions)
1959In 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.

1990
The preceding chapter outlined some of the elements of quantum scattering theory. Almost nothing was said about the ways in which the physics of the nucleus influence the parameters which enter the formal theory, although some general features of nuclear reactions were discussed briefly in Chapter 2. We now intend to describe various physical models in

A collective model for the nuclear photo-reactions
Il Nuovo Cimento, 1956For the nuclear photo-reaction in the giant resonance region, we considered a collective model which includes both the Goldhaber-Teller and Steinwedel-Jensen type of motion. We find a coupling of these two modes through the kinetic energy. This leads us to two resonance frequencies.

Challenges beyond Hauser-Feshbach for nuclear reaction modeling [PDF]
European Physical Journal A, 2015 We discuss deficiencies in the statistical Hauser-Feshbach theory implemented into the available computer codes, and possible extension of reaction calculations in the next decade, which are particularly important to nuclear data studies. The discussions

Cascade-exciton model of nuclear reactions
Nuclear Physics A, 1983Abstract 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
2020EMPIRE 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.

TALYS: Comprehensive Nuclear Reaction Modeling
AIP Conference Proceedings, 2005TALYS is a nuclear‐reaction program which simulates nuclear reactions that involve neutrons, gamma‐rays, protons, deuterons, tritons, helions, and alpha‐particles, in the 1 keV – 200 MeV energy range. A suite of nuclear‐reaction models has been implemented into a single code system, enabling us to evaluate basically all nuclear reactions beyond the ...

A schematic model for the investigation of nuclear reactions
Nuclear Physics A, 1976Abstract An extension of the schematic model of Lipkin, Glick and Meshkov to include reaction modes with one particle in the continuum is introduced. The model set up is amenable to the investigation of various approximations necessary in realistic shell model in the continuum calculations.
