Calculation of the radiance distribution at the boundary of an isotropically scattering slab [PDF]

, 1997
The radiance arising from an anisotropically scattering illuminated stack of n slabs is calculated using the equation of radiative transfer. It appears to be unnecessary to calculate the radiance inside the material; including only the radiance at the ...

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.

The Influence of Neighbouring Clouds on the Clear Sky Reflectance Studied with the 3-D Transport Code RADUGA

, 2005
Operational remote sensing of terrestrial atmosphere is heavily based on the 1-D radiative transfer equation. However, cloudy scenes are influenced by 3-D effects (e.g., illumination from cloud sides, etc.).

Modified F N solution of the neutron transport equation for the Milne problem with FBIS kernel

, 2019
The solution of the Milne problem is studied by one-speed neutron transport equation in plane geometry with İnönü’s scattering kernel, which is known as a linear combination of the forward, backward and isotropic scattering kernel (FBIS kernel).

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
