DIFF, a code to prepare neutron diffusion theory parameters from the results of the code WDSN.

open access: yes, 1967
With a solution of the multigroup neutron transport equation available for a problem in one dimensional geometry, diffusion theory parameters are determined so as to reproduce in diffusion theory the essential characteristics of the transport solution ...

Investigation of Neutron Diffusion Length in Wax Medium [PDF]

open access: yes, 2011
The investigation of the damage tracks of Pu (Be) neutron source by using solid state nuclear track detector in the wax medium was performed. Using the neutron tracks and neutron diffusion equation, neutron diffusion length in wax medium was ...

Disorder‐Driven Fast Na+ Transport: From Crystalline to Amorphous Networks in the Mixed‐Anion NaTaOxCl6−2x Oxychlorides

open access: yesAdvanced Energy Materials, EarlyView.
Oxygen substitution in NaTaOxCl6‐2x drives structural evolution from isolated [TaCl6]– octahedra, through oxygen‐bridged [Ta2OCl10]2– dimers, toward extended trans‐[TaO2Cl4]3– chain‐like arrangements. At intermediate compositions, zero‐dimensional corner‐sharing motifs are proposed to create a flexible, disordered framework that peaks ionic ...

La diffusion des neutrons [PDF]

open access: yesRevue de Physique Appliquée, 1976
On rappellera les bases physiques de la diffusion des neutrons en insistant sur les caractéristiques du phénomène qui la différencie de la diffusion des rayons X, en particulier l'existence d'une diffusion inélastique dont le spectre en énergie peut être déterminé.

Accuracy of the diffusion theory component of removal-diffusion theory.

open access: yes, 1976
The neutron fluxes in five neutron shields consisting of water, concrete, graphite, iron and an iron-water lattice respectively, have been calculated using P1 theory, diffusion theory with the usual transport correction for anisotropic scattering (DT ...

Silicon‐Based Anodes for Sulfide Solid‐State Batteries: Failure Mechanisms and Multiscale Design Strategies

open access: yesAdvanced Energy Materials, EarlyView.
Silicon anodes in sulfide SSBs face coupled electrochemo‐mechanical failure by interface instability. This review examined recent advances and proposed mitigation strategies via material‐, electrode/interface‐, and cell‐level‐ engineering. We further evaluate scalable synthesis of sulfide SEs.

Role of neutron transfer and deformation effect in capture process at sub-barrier energies

open access: yesEPJ Web of Conferences, 2012
The roles of nuclear deformation and neutron transfer in sub-barrier capture process are studied within the quantum diffusion approach. The change of the deformations of colliding nuclei with neutron exchange can crucially influence the sub-barrier ...

A new moving-mesh Finite Volume Method for the efficient solution of two-dimensional neutron diffusion equation using gradient variations of reactor power

open access: yesNuclear Engineering and Technology, 2019
A new moving-mesh Finite Volume Method (FVM) for the efficient solution of the two-dimensional neutron diffusion equation is introduced. Many other moving-mesh methods developed to solve the neutron diffusion problems use a relatively large number of ...
