X-ray microscopy by successive Fourier transformation II. An optical analogue experiment
(Elsevier, 1966-06-01)
An optical analogue experiment related to a method of X-ray microscopy by successive Fourier transformation is described. Some experimental design features are discussed.
Vortex wheels in superfluid helium
(Elsevier, 1968-06-17)
It is suggested that the continuous reversal of apparent circulation around a vibrating wire in liquid He II is due to the motion of a vortex-line array called a "vortex wheel".
Electromagnetic radiation from a source in a plasma
(Elsevier, 1961-11)
The problem of determining the electromagnetic radiations from a given charge-current distribution situated in a plasma in the presence of a uniform external magnetic field is solved. Explicit expressions for the asymptotic ...
Some results on many-body scattering theory
(Elsevier, 1968-09)
Several problems are considered related to the study of the T-matrix in the manybody scattering situation. Expanding previous results, the T-matrix is studied outside the realm of perturbation theory, with relation to ...
On the fermi approximation in thermal neutron scattering
(Elsevier, 1964-01)
The Fermi approximation and all higher order corrections are derived for the cross section for thermal neutron scattering from aggregates of atoms. The first order correction is shown to reduce to the result obtained by ...
Orthogonality of case's eigenfunctions in one-speed transport theory
(Elsevier, 1964-12)
The eigenfunctions of the one-speed transport equation, as introduced by Case, are shown to have more general orthogonality properties than previously known. In particular, for isotropic scattering, partial range and ...
Logarithmic corrections to the theory of the [lambda]-transition in 4He
(Elsevier, 1968-11-18)
The logarithmic singularity in the specific heat is used to investigate the logarithmic corrections to the phenomenological theory of the [lambda]-transition in liquid helium-4. A justification of the theory of Mamaladze ...
125Te Mossbauer effect study of magnetic hyperfine structure in the ferromagnetic spinel CuCr2Te4
(Elsevier, 1967-11-20)
The Mossbauer hyperfine spectrum of 125Te has been measured in the ferromagnetic spinel CuCr2Te4. The hyperfine field was found to be 148 +/- 5 kOe. The nuclear magnetic moment of the 35.6 keV excited state of 125Te was ...
