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 ...

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.

Computational model for nuclear reaction studies: Quasiparticle dynamics
Physical Review C, 1988A computation model for nuclear reaction studies which is based upon a momentum dependent interaction between quasiparticles is extended to include collisions between the nucleons. The model is first used to examine the time scales involved in fragment formation at intermediate energies, both as a function of bombarding energy and impact parameter. The

Renormalization for optical model and unified model of nuclear reactions
Physical Review C, 1993A unified model of nuclear reactions taking account of both the compound and preequilibrium nuclear reactions is proposed in terms of a renormalization of the wave functions generated by the optical model potential. The cross sections of the nuclear reactions including preequilibrium processes are formulated, which are especially suited for ...

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

On the optical model for nuclear reactions
Il Nuovo Cimento, 1958The complex potential for neutrons in an infinite nuclear medium is computed in a perturbation calculation up to the second order, using for the nucleon-nucleon interaction a regular potential which fits the low energy two-body data. It is shown that it is possible to fit simultaneously the real and the imaginary part of the optical potential and the ...

Nuclear potentials model for heavy-ion reactions
New Astronomy, 2019Abstract Here, we present a nuclear potential model for heavy- ion reactions consisting of four central, spin, iso-spin and Iτ terms. The potential model presented here, predicts more accurate values for the barrier height of 6Li+24Mg→30P* and 7Li+24Mg→31P* reactions compared to the other potential models such as Proximity potential (Prox.77 and Prox.

Unitary Models of Nuclear Resonance Reactions
Physical Review, 1967While most reaction theories are formally flux conserving, the kinds of models and approximations used to specify the $S$ matrix for resonance reaction processes are often of doubtful unitarity, particularly in the overlapping resonance region. To investigate the consequences of unitarity in this domain, several classes of simple analytically specified

Three-body model for stripping nuclear reactions
International Journal of Theoretical Physics, 1984A three-body model for the deuteron stripping nuclear reactions is presented. A set of three integral equations is obtained for the wave functions of the three-body problem by introducing a decomposition into angular momentum states into the Lippmann-Schwinger equation. Simple two-particle interactions with separable potentials are used.

Hybrid Model for Pre-Equilibrium Decay in Nuclear Reactions
Physical Review Letters, 1971Ideas from Griffin's exciton model are combined with those from the nucleon-nucleon scattering approach to nuclear transition times to provide a simple closed-form expression for predicting pre-equilibrium decay phenomena, including variation of pre-equilibrium emission with target mass, excitation energy, and initial particle and hole numbers.
