Discrete ordinates (SN) method for the first solution of the transport equation using Chebyshev polynomials

EPJ Web of Conferences, 2016
First estimates for the numerical solution of the one-dimensional neutron transport equation for one-speed neutrons in a finite homogeneous slab is studied. The neutrons are assumed to be scattered isotropically through the medium.

Isospin Diffusion in Heavy-Ion Collisions and the Neutron Skin Thickness of Lead

, 2005
The correlation between the thickness of the neutron skin in Pb-208, and the degree of isospin diffusion in heavy-ion collisions is examined. The same equation of state is used to compute the degree of isospin diffusion in an isospin-depedent transport ...

Structural Aspects of Neutron Survival Probabilities

Journal 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 ...

Hyperons in Neutron Stars

Universe, 2021
I review the issues related to the appearance of hyperons in neutron star matter, focusing in particular on the problem of the maximum mass supported by hyperonic equations of state. I discuss the general mechanism that leads to the formation of hyperons

Probing the nuclear EOS with fragment production

, 2007
We discuss fragmentation mechanisms and isospin transport occurring in central collisions between neutron rich systems at Fermi energies. In particular, isospin effects are analyzed looking at the correlations between fragment isotopic content and ...

Nuclear equation of state at high density and the properties of neutron stars [PDF]

, 2000
We discuss the relativistic nuclear equation of state (EOS) using a relativistic transport model in heavy-ion collisions. From the baryon flow for $Au + Au$ systems at SIS to AGS energies and above we find that the strength of the vector potential has to

Invariant Imbedding and Neutron Transport Theory II-Functional Equations [PDF]

Indiana University Mathematics Journal, 1958
No abstract. 13:000396A procedure is developed for obtaining, in nuclear shell theory, the matrix elements associated with short range interactions between nucleons. It is shown that potentials of arbitrary range, both central and spin dependent, can be developed in terms of a series of velocity dependent potentials in increasing powers of the momentum,

Accelerated solution methods for self-adjoint angular flux neutron transport equations based on scattering matrix decoupling

Nuclear Engineering and Technology
Advanced microreactors exhibit compact geometries, elevated neutron leakage, and pronounced anisotropic scattering. These characteristics necessitate high-fidelity neutron transport methods to accurately resolve core flux distributions.

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

Yuanzineng 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.
