Superconductivity and the Electron-Phonon Interaction in Transition Metals( Book )

2 editions published in 1970 in English and held by 2 WorldCat member libraries worldwide

Formulas are given both for the volume dependence of the transition temperature Tc of transition metals and for the Tc of well-ordered A15 compounds. Both formulas yield results in reasonable agreement with experiment. Measurements are proposed to facilitate further comparison with experiment. Hopfield's explanation of the high Tc of some A15 compounds is supported. Finally, it is shown why phonon-softening effects are unlikely to yield high transition temperatures for transition metals or transition-metal compounds. (Author)

Coherence Effects in the Detection of Weak Light Signals( Book )

1 edition published in 1974 in English and held by 1 WorldCat member library worldwide

This final report describes research carried out on the problem of detecting a weak light beam by the heterodyne method, and on the phase retrieval problem. It has been shown that Siegman's antenna theorem does not provide the principal limitation on the detectability of a weak light signal, and that, in general, there exists an optimum detector size that depends on the orientation of the detector. On the basis of this conclusion, it is suggested that a search for an unknown light signal be conducted with a detector of variable aperture. With the help of certain analytic properties of optical wave functions, it has been shown that the phase distribution of an optical image can be derived from measurements of the light intensity distribution
Generalized Fourier Techniques for the Theory of Light Scattering( Book )

1 edition published in 1971 in English and held by 1 WorldCat member library worldwide

The report presents a review of research carried out under the contract. The work was chiefly concerned with the development of systematic techniques for determining the structure of three-dimensional semi-transparent objects from the measurements of transmission functions of holograms to which these objects give rise when they are illuminated by light beams. Related work was also carried out on some analogous problems involving sound waves rather than light waves and on several problems involving the angular spectral representation of wavefields. The report includes references to all publications reporting results of this research, abstracts of all the publications and list of personnel that assisted with this work. (Author)
Investigations by analytic and theoretical procedure of visibility functions( Book )

1 edition published in 1970 in English and held by 1 WorldCat member library worldwide

The work was chiefly concerned with procedures of recovering spectral and other information from visibility functions and with a number of closely related questions of optical coherence theory. (Author)
A model for the origin and properties of the cosmic ray rigidity spectrum by M. F Kaplon( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

A model is proposed to explain a number of features of the differential rigidity spectra of the nuclear component of the primary cosmic radiation. A supernova explosion is assumed to result in the acceleration of nuclei to a pure power law rigidity spectrum and a composition relatively rich in heavy and medium weight nuclei. The supernova remnant into which these particles are injected is characterized as a large scale trapping region resulting from predominantly closed magnetic field lines which partially isolate the region from the surrounding galactic space. This feature of the supernova region is represented by a dipole-like field. Superimposed on this field we assume that magnetic irregularities produce a certain amount of distortion of the field lines in the interior of the source; and irregularities along the periphery of the source lead to local distortions of the field and hence, a mixing of galactic and source field lines in the neighborhood of these irregularities.

Theory for the Pressure Dependence of Tc for Narrow-Band Superconductors( Book )

1 edition published in 1971 in English and held by 1 WorldCat member library worldwide

A theory for the pressure dependence of T sub c in narrow-band superconductors is proposed. New physical mechanisms which in transition metals lead to an increase under pressure in the Hopfield parameter eta and in some cases even an increase in T sub c are discussed. It is shown how investigations of the pressure dependence of T sub c may give information on the importance of lattice instability and/or spin fluctuations on T sub c. Approximate calculated values of the partial derivative of (T sub c) with respect to p are presented for all of the superconducting transition-metal elements and for a few compounds. (Author)

Localized Perturbation Hamiltonian and the Friedel Sum Rule( Book )

1 edition published in 1971 in English and held by 1 WorldCat member library worldwide

It is shown that the localized perturbation model Hamiltonian is consistent with the Friedel Sum Rule obtained using charge neutrality arguments. The authors conclude that the localized perturbation model appears to be applicable to real physical systems, which result contradicts the conclusions of a recent paper by Stern. (Author)

HIGH ENERGY COSMIC GAMMA RADIATION( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

A sequence of ten balloon-borne experiments was designed to detect gamma rays by conversion in lead. The counter telescopes were sensitive to radiation from directions near zenith; nominal acceptance cones of 10 degrees, 30 degrees, and 60 degrees have been used. Seven of the flights produced useful data at high altitude, with results in three classes: i) an isotropic background flux of at least .0006 gamma/sq cm -sec-ster which may be of primary origin; ii) an anomalous flux from 20 hr. right ascension and +30 degrees declination, with an intensity of at least .0002 gamma/sq cm-sec; and iii) several short time variations of gamma ray and charged particle fluxes. There is as yet no explanation for the time variations, but similar effects have recently been reported from another experiment at lower energy. (Author)

Coupling and recoupling of relativistic states. ii. note on the systematics of many particles systems( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

The direct product of many irreducible representations of the Poincare group is discussed. A procedure is suggested for the decomposition in the canonical scheme, which is not an iteration of the 2-particles method. Also, it is independent of the c.m.s. Corresponding expression for S-matrix elements of many particle processes is given. The properties of the invariant functions associated with elastic scattering in case of parity, time reversal and crossing symmetries is discussed, as well as in case of identical particles. (Author)
