Sobolev Regularity in Neutron Transport Theory [PDF]

ISRN Mathematical Analysis, 2012
The main purpose of this paper is to extend the W1,p regularity results in neutron transport theory, with respect to the Lebesgue measure due to Mokhtar-Kharroubi, (1991), and to abstract measures covering, in particular, the continuous models or multigroup models.

Invariant Imbedding and Neutron Transport Theory IV-Generalized Transport Theory [PDF]

Indiana University Mathematics Journal, 1959
Abstract : The aim of the paper is to extend previous results and techniques so as to include an extensive category of transport processes involving deterministic and stochastic interactions and general geometries. Characteristic func tions and probabilities as well as expected values (fluxes) are determined. (Author)

Application of the improved quasi-static coupled probability theory method to transient safety analysis of an experimental facility

Frontiers in Energy Research, 2023
The accelerator-driven sub-critical system is driven by external neutron sources, which are generated by the spallation reaction and maintain the stable operation of the sub-critical core, while the external neutron source increases the complexity of ...

Nucleon-nucleon momentum correlation function for light nuclei [PDF]

, 2006
Nucleon-nucleon momentum correlation function have been presented for nuclear reactions with neutron-rich or proton-rich projectiles using a nuclear transport theory, namely Isospin-Dependent Quantum Molecular Dynamics model. The relationship between the

Isospin Distillation with Radial Flow: a Test of the Nuclear Symmetry Energy [PDF]

, 2007
We discuss mechanisms related to isospin transport in central collisions between neutron-rich systems at Fermi energies. A fully consistent study of the isospin distillation and expansion dynamics in two-component systems is presented in the framework of

Combining density functional theory and Monte Carlo neutron transport calculations to study the phonon density of states of UO2 up to 1675 K by inelastic neutron scattering

Physical review B, 2020
Significant advances in the use of atomistic simulation techniques, such as ab initio density functional theory and the molecular dynamics method, made it possible to predictively calculate properties of materials.

A NOVEL COARSE-MESH METHOD APPLIED TO NEUTRON SHIELDING PROBLEMS USING THE MULTIGROUP TRANSPORT THEORY IN DISCRETE ORDINATES FORMULATIONS

Brazilian Journal of Radiation Sciences, 2021
In this paper, we propose a new deterministic numerical methodology to solve the one-dimensional linearized Boltzmann equation applied to neutron shielding problems (fixed-source), using the transport equation in the discrete ordinates formulation (SN ...

Low mass binary neutron star mergers : gravitational waves and neutrino emission [PDF]

, 2016
Neutron star mergers are among the most promising sources of gravitational waves for advanced ground-based detectors. These mergers are also expected to power bright electromagnetic signals, in the form of short gamma-ray bursts, infrared/optical ...

Anomalous hydrodynamics kicks neutron stars

Physics Letters B, 2016
Observations show that, at the beginning of their existence, neutron stars are accelerated briskly to velocities of up to a thousand kilometers per second.

Magnetic Properties of Heavy Fermion Superconductors CeRhIn5 and Ce2RhIn8 [PDF]

, 2002
Some recent neutron scattering works on CeRhIn5 and Ce2RhIn8, together with related resistivity and specific heat measurements, are summarized. In spite of its layered crystal structure, CeRhIn5 is shown to be 3-dimensional both magnetically and in ...
