Transport Properties of Superfluid Phonons in Neutron Stars

Universe, 2021
We review the effective field theory associated with the superfluid phonons that we use for the study of transport properties in the core of superfluid neutrons stars in their low temperature regime.

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

Invariant Imbedding and Neutron Transport Theory III-Neutron-Neutron Collision Processes [PDF]

Indiana University Mathematics Journal, 1959
Abstract : The effects on criticality of neutron-neutron collisions involving annihilation are investigated for one-dimensional, single and multi-group cases. The analytic treatment shows that regardless of the magnitude of the cross section for collision between moving neutrons, there is no critical length (mass).

Spectral-Nodal Deterministic Methodology for Neutron Shielding Calculations using the X, Y - geometry Multigroup Transport Equation in the Discrete Ordinates Formulation

Vetor, 2021
In this work, we present the most recent numerical results in a nodal approach, which resulted in the development of a new numerical spectral nodal method, based on the spectral analysis of the multigroup, isotropic scattering neutron transport equations

Neutron angular flux reconstruction in slab geometry using multigroup discrete ordinates transport models

Brazilian Journal of Radiation Sciences, 2023
In this article, we present an application of the coarse-mesh Deterministic Spectral Method (SDM) to generate multigroup angular fluxes in one-dimensional spatial domains using the neutron transport stationary equation, in the formulation of discrete ...

Coherence Effects and Neutrino Pair Bremsstrahlung in Neutron Stars [PDF]

, 1999
We calculate the rate of energy radiation by bremsstrahlung of neutrino pairs by baryons in neutron stars employing a transport model in which neutrinos couple to baryons with spectral width.

Preliminary Study on the Thermal Neutron Scattering Cross-Section for HinH₂O in Small Modular Reactors

Journal of Nuclear Engineering, 2023
Neutron thermalization leads to the complexity of the scattering cross-section calculation, which influences the accuracy of the neutron transport calculation in the thermal energy range. The higher precision of thermal scattering data is demanded in the

Constraining gravity with hadron physics: neutron stars, modified gravity and gravitational waves

EPJ Web of Conferences, 2017
The finding of Gravitational Waves (GW) by the aLIGO scientific and VIRGO collaborations opens opportunities to better test and understand strong interactions, both nuclear-hadronic and gravitational.

Magnetic Field Generation in Stars [PDF]

, 2015
Enormous progress has been made on observing stellar magnetism in stars from the main sequence through to compact objects. Recent data have thrown into sharper relief the vexed question of the origin of stellar magnetic fields, which remains one of the ...
