Microscopic optical potentials for $^4$He scattering

, 2014
We present a reliable double-folding (DF) model for $^{4}$He-nucleus scattering, using the Melbourne $g$-matrix nucleon-nucleon interaction that explains nucleon-nucleus scattering with no adjustable parameter. In the DF model, only the target density is

Low-energy neutron-deuteron reactions with N3LO chiral forces [PDF]

, 2014
We solve three-nucleon Faddeev equations with nucleon-nucleon and three-nucleon forces derived consistently in the framework of chiral perturbation theory at next-to-next-to-next-to-leading order in the chiral expansion.

Simulation of Galactic Cosmic Ray Proton Fluxes With the Daily Modulation Parameter: Validation With AMS‐02 Data for 2011–2019

Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.
Abstract The flux of galactic cosmic rays (GCRs) is modulated by solar activity on different time scales. This is often described with the force‐field approximation via the single variable parameters of the modulation parameter, which formally corresponds to the average rigidity loss of GCR particles in the heliosphere. The force‐field approximation is

Calculation of Neutron Induced Nuclear Reaction on Deuteron with Faddeev Equation

Yuanzineng kexue jishu, 2022
Neutron induced nuclear reaction on light nuclei is an important subject in nuclear data research. The reaction of the n+d three nucleons system is also an important platform for examining the nucleonnucleon interaction theories.

Optical Potentials: Microscopic vs. Phenomenological Approaches [PDF]

EPJ Web of Conferences, 2019
In this work we study the performances of our microscopic optical potential [1, 2], derived from nucleon-nucleon chiral potentials at fifth order (N4LO), in comparison with those of a successful non-relativistic phenomenological optical potential in the ...

Mean free paths and in-medium scattering cross sections of energetic nucleons in neutron-rich nucleonic matter within the relativistic impulse approximation

, 2007
The mean free paths and in-medium scattering cross sections of energetic nucleons in neutron-rich nucleonic matter are investigated using the nucleon optical potential obtained within the relativistic impulse approximation with the empirical nucleon ...

Tensor representation of the nucleon-nucleon amplitude [PDF]

, 2001
Many approaches to nucleon-nucleus elastic and inelastic scattering are based on the use of the free-space nucleon-nucleon transition amplitude. In calculations where the full spin-dependence of this amplitude is needed, its use is more tractable when it

Final State Interaction in Exclusive $(e,e'NN)$ Reactions [PDF]

, 2000
Contributions of nucleon-nucleon (NN) correlations, meson exchange currents and the residual final state interactions (FSI) on exclusive two-nucleon knock-out reactions induced by electron scattering are investigated.
