In-situ and Kinetic Studies Using Neutrons
2014Neutrons provide unique possibilities for in-situ studies of condensed matter due to their ability to penetrate large samples and work pieces, to distinguish between neighboring elements and even between isotopes of the same element, to interact with magnetic moments and to map nuclear and magnetic excitations.

Existence Result for the Kinetic Neutron Transport Problem in the Presence of Delayed Neutrons
Transport Theory and Statistical Physics, 2006We propose a new proof of existence result concerning the kinetic neutron transport equation. The proof is constructive in the sense that we build a sequence that converges to the solution of the problem by iterating on the collision terms. We consider the kinetic problem in the presence of delayed neutrons and we take into account the time dependence ...

Topology of Linear Neutron Kinetics
Nature, 1961In the theory and interpretation of pulsed neutron measurements and in the analysis of random fluctuations in a nuclear fission reactor it is often helpful to study the kinetic behavior of the time-dependent, space-independent model of the multiplying assembly.

Effect of Delayed Fission Neutrons on Reactor Kinetics
Journal of Applied Physics, 1955A detailed treatment of reactor kinetics is given. The kinetic equations are derived from a diffusion-Fermi age model. An iterative technique and a matrix method are discussed as possibilities for obtaining solutions. The relationship between the solutions with and without delayed neutrons is pointed out.

On the Fractional Neutron Point Kinetics Equations
2013This work proposes a fractional derivative model for some anomalous neutron diffusion phenomena in nuclear reactors. The model is solved in terms of the neutron flux density and current. The fractional diffusion model displayed may be applied to large variations neutron cross-section that normally prevent the use of the classic model of the neutron ...

Prompt-Neutron Kinetics of a Spherical-Cavity Reactor
Nuclear Science and Engineering, 1967A simple kinetics model is proposed that describes time dependence of the prompt-neutron population in a cavity reactor in terms of a linear, first-order differential equation for the net thermal-n...

Nonstationary problems in the kinetic theory of neutron transport
Soviet Atomic Energy, 1964The nonstationary kinetic equation for monoenergetic neutrons is solved by an application of a Fourier transformation of the unknown function and the source function, taking account of initial data. Detailed consideration is given to the problem of the distribution of neutrons from a moving or oscillating source.
