Study of Monte Carlo Simulation Method for Proton Transport in NPTS Program

open access: yesYuanzineng kexue jishu, 2023
Monte Carlo simulation has become an effective method for solving different physical problems, which is especially advantageous in the particle transport problems with complex geometric models.

Asymmetric nuclear matter in a Hartree-Fock approach to non-linear QHD [PDF]

open access: yes, 2000
The Equation of State (EOS) for asymmetric nuclear matter is discussed starting from a phenomenological hadronic field theory of Serot-Walecka type including exchange terms.

Collisions of Nucleons with Atoms: Calculated Cross Sections and Monte Carlo Simulation

open access: yesFrontiers in Physics, 2021
After a summary description of the theory of elastic collisions of nucleons with atoms, we present the calculation of a generic database of differential and integrated cross sections for the simulation of multiple elastic collisions of protons and ...

Finite temperature effects on cosmological baryon diffusion and inhomogeneous Big-Bang nucleosynthesis [PDF]

open access: yes, 1998
We have studied finite temperature corrections to the baryon transport cross sections and diffusion coefficients. These corrections are based upon the recently computed renormalized electron mass and the modified state density due to the background ...

On the number of solutions of some integral equations arising in radiative transfer

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1989
We discuss the number of solutions of some nonlinear integral equations arising in the theories of radiative transfer, neutron transport and in the kinetic theory of gases.

Structural Aspects of Neutron Survival Probabilities

open access: yesJournal of Nuclear Engineering
The neutron survival probability (and related quantities including probabilities of extinction and initiation) is a central element of the broader stochastic theory of neutron populations and finds application in fields including reactor start-up ...

Classical and quantum many-body description of bremsstrahlung in dense matter (Landau - Pomeranchuk - Migdal effect) [PDF]

open access: yes, 1995
Some considerations about the importance of coherence effects for bremsstrahlung processes in non--equilibrium dense matter (Landau - Pomeranchuk - Migdal - effect) are presented.

Development and Verification of Hexagonal Quasi-diffusion Code Based on Variational Nodal Method

open access: yesYuanzineng kexue jishu, 2023
New type reactors usually adopt advanced fuel types and more anisotropic fuel arrangements, the neutron spectrum is very different from that of pressurized water reactor, and the neutron anisotropy is stronger.

Heat Transport and Convective Velocities in Compositionally Driven Convection in Neutron Star and White Dwarf Interiors

open access: yesThe Astrophysical Journal, 2023
We investigate heat transport associated with compositionally driven convection driven by crystallization at the ocean–crust interface in accreting neutron stars, or growth of the solid core in cooling white dwarfs.
