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 ...

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.

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.

Transport Coefficients of Hyperonic Neutron Star Cores

open access: yesUniverse, 2021
We consider transport properties of the hypernuclear matter in neutron star cores. In particular, we calculate the thermal conductivity, the shear viscosity, and the momentum transfer rates for npΣ−Λeμ composition of dense matter in β–equilibrium for ...

Neutron total cross section calculation within the framework of quasi-harmonic approximation

open access: yesNew Journal of Physics, 2017
The accuracy of neutron scattering cross sections is the gauge for the realistic outcome of a neutron transport simulation. To improve the traditional harmonic physics model used in such simulations, we revisit the slow neutron transport theory in ...

Non-classical transport with angular-dependent path-length distributions. 2: Application to pebble bed reactor cores

open access: yes, 2013
We describe an analysis of neutron transport in the interior of model pebble bed reactor (PBR) cores, considering both crystal and random pebble arrangements.

Using software based on the Monte-Carlo method for receiving the few-group homogenized macroscopic interaction cross-section

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2017
The constant preparation issues are important for performing the few-group analysis for different states of the reactor core. Besides, the constant preparation method influences the further calculations accuracy and quality.
