Modified slater integrals for an ion in a solid
(Elsevier, 1967-05-22)
Expressions for the Slater integrals are derived for an ion of the first transition series when placed in a solid. Reasonable agreement is obtained with experimental data for Co++ in spinel.
A discrete ordinates solution of the Fokker-Planck equation characterizing charged particle transport
(Elsevier, 1980-11-01)
A formalism for obtaining a discrete ordinates solution of the time and space-dependent Fokker-Planck equation governing the transport of charged particles in multispecie plasmas is developed. In the absence of macroscopic ...
Application of the Sherman-Morisson formula to scattering problems by multi-component systems
(EDP Sciences, Springer-Verlag, Società Italiana di Fisica, 2002-06)
The scattering matrix for multi-component systems is recalculated using the extended form of the Sherman-Morisson formula. The matrix elements are given explicitly in closed form. The Gibbs-Duhem relation separates the ...
Paramagnetic resonance of erbium in CaWO4
(Elsevier, 1968-12-02)
A study has been made of the paramagnetic resonance of Er3+ in single crystal CaWO4. and the parameters of the spin-Hamiltonian determined.
A test particle approach in the stochastic stability analysis of charged particle beams
(Elsevier, 1990-01-15)
The stochastic stability of a charged particle beam propagating in a randomly unhomogeneous medium is analyzed using an internal test particle approach. The effect of the random medium is included by adding a stochastic ...
Spectral representations for the memory kernel characterizing self-diffusion
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1974-11)
Approximate spectral representations are developed for the memory kernel which characterizes self-diffusion. These spectral representations are based upon approximate eigenfunctions constructed via the Rayleigh variational ...
Photon transport theory
(Elsevier, 1961-08)
A first order, momentum-configuration space transport equation for photons is derived for low energy (nonrelativistic) systems. The derivation is first order in the sense that the transition probabilities characterizing ...
Motion of a charged particle in a randomly varying magnetic field
(Elsevier, 1985-07)
The motion of a charged particle in a randomly varying uniform magnetic field is investigated. Stability of the mean position and mean square displacement are determined rigorously in the case of random binary variations ...
A comparison of projection operator formalisms for the study of self-diffusion
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1973-11)
The utility of projection operator formalisms for describing the dynamics of many-body systems is studied, and the compatibility of these formalisms with certain approximation schemes is evaluated in the light of known ...
Solution of the Fokker-Planck transport equation by matrix factorization
(Elsevier, 1981-08)
A matrix factorization method is used to solve the Fokker-Planck (Landau) charged particle transport equation. By treating all phase space variables as discrete in analogy to Sn neutronics, the collision term takes on a ...
