The Nature of the Axioms of Relativistic Quantum Field Theory

"The formulation of field theories by means of Wightman functions is studied. It is shown that, given two field theories that satisfy all the axioms, one can construct a family of Wightmsn fields with the same properties by a process of superposition of Wightman functions. The condition of unitarity is formulated without reference to asymptotic conditions, and it is proved that the Wightman fields constructed by the superposition process (starting with "unitary" fields) fail to preserve unitarity."

Cobalt (II) Halides as Electrolytes in Acentonitrile (open access)

Cobalt (II) Halides as Electrolytes in Acentonitrile

"The electrical conductance of CoCl2 and CoBr2 from 10−4 to 10−1 mol/l over the temperature range 0–35°C is reported. The effects of water as trace impurity, and the halide common ion effect on conductance are examined. The properties of these solutes are also examined using spectrophotometry and transport numbers. Crystalline “solvated” compounds, of empirical formulae [CoX2(CH3CN)3]x can be separated from the saturated solutions. The magnetic susceptibilities of the crystalline substrates are in accord octahedral and tetrahedral symmetry for the cationic and anionic species in these “solvates”, the bonding in both being the spin-free type for divalent cobalt. From the optical properties of the solutions it is apparent that the “anomalous” properties of these electrolytes can be understood in a series of simultaneous processes under Mass-Law control, in which CoX2, CoX42−, Co(CH3CN)62+ and [Co(CH3CN) 62+CoX42−]° are predominant."

The Proton-Proton Triple Scattering Parameters R and A at 213 Mev (open access)

The Proton-Proton Triple Scattering Parameters R and A at 213 Mev

"As a part of a program to determine the p-p scattering matrix at 213 Mev, the triple scattering parameters R and A were measured at 30, 40, 50, 60, 70, 80. and 90 deg in the center-of-msss system. The results are compared with a phase shift analysis by MacGregor and Moravcsik and with the predictions of the boundary condition model of Saylor, Bryan and Marshak."

The Lepton Decay Nodes of Hyperons (open access)

The Lepton Decay Nodes of Hyperons

"In spite of the present scarcity of experimental data it appears likely that the lepton modes of hyperon decay will eventually become an important source of information concerning strangeness-changing weak interactions. In this paper we use dispersion relations to estimate the effect of intermediate meson states upon the lepton decay modes of hyperons."

A Theoretical and Experimental Study of Optical Fibers (open access)

A Theoretical and Experimental Study of Optical Fibers

A geometrical treatment has been used to outline the theoretical properties of optical fibers which are imperfect as well as geometrically and optically perfect. Experiments have been performed to measure some to the optical properties of individual fibers and fiber bundles.

Conical Refraction in Crystal Optics and Hydromagnetics (open access)

Conical Refraction in Crystal Optics and Hydromagnetics

When light propagates with the wave normal in the direction of an optic axis of a biaxial crystal, the usual ray theory breaks down. This phenomenon can be analyzed by means of an asymptotic solution of Maxwell's equations. The intensity is governed by a partial differential equation within the phase surfaces, instead of ordinary differential equations along rays. This example slows that light does not always propagate along rays. A similar phenomenon occurs in hydromagnetics.
