Close-in Air Blast from a Row Charge in Basalt

From abstract: Close-in air blast measurements were made on the Dugout shot. Major constituents of the blast wave were the ground-shock-induced pulse and the pulse from venting gases. The ground-shock-induced pulse was the dominant one at all stations.

Computer Programs Using Zonal Harmonics for Magnetic Properties of Current Systems with Special Reference to the IBM 7090

Report that "discusses the magnetic vector and scalar potentials, magnetic field components and their derivatives, and flux linkage for single current systems, and the mutual inductance, forces and torques between two such systems, whose axes are coplanar but not necessarily coincident" (p. 1).

Cosmogenic Carbon-14 and Chlorine-36 in Meteorites (open access)

Cosmogenic Carbon-14 and Chlorine-36 in Meteorites

In 1947 Bauer, and later independently Huntley (1948), pointed out that the helium content of iron meteorites as measured by Paneth and coworkers could be accounted for by the accumulation through cosmic-ray production rather then the decay of uranium and thorium. Bauer (1947) also predicted that the meteroitic helium should contain a significant proportion of He3. I was realized that by studying the effects of cosmic radiation on meteorites much could be learned about the history of meteorite and cosmic radiation. Chemical and instrumental techniques have been developed for the isolation, purification, and measurement of cosmic-ray-induced C14 in both stone and iron meteorites. The isolation of carbon from the silicate materials is done by fusion in an oxidizing flux in a vacuum system. From the iron meteorites the carbon is recovered by the decomposition of the metal in nitric acid in a closed system.

A Hooded and Ion Source With a Magnetic Mirror Feature (open access)

A Hooded and Ion Source With a Magnetic Mirror Feature

"The ion source used for hydrogen and deuterium ions in the variable energy cyclotron at the University of Rochester is of the hooded arc type. For the past year it has been operating with a new feature which has greatly improved its performance. The new feature is a magnetic mirror built into the upper end of the arc hood by a simple insertion of a steel bearing ball 1/8" in diameter. The magnetic field gradient near the ball provides a magnetic mirror action on electrons moving up the arc channel toward the ball, reflecting may of them."

Propagation Characteristics of Capillary Ripples, I. The Theory of Velocity Dispersion and Amplitude Attenuation of Plane Capillary Waves on Viscoelastic Films (open access)

Propagation Characteristics of Capillary Ripples, I. The Theory of Velocity Dispersion and Amplitude Attenuation of Plane Capillary Waves on Viscoelastic Films

From abstract: "The boundary value problem for velocity of propagation and attenuation of capillary ripples over viscoelastic surface films is set up and solved from the viewpoint of continuum hydrodynamics. Both soluble and insoluble films are treated. Successive approximation methods are used to derive explicit formulae for velocity of propagation and amplitude attenuation; formulae for these quantities accurate to second order are given for slightly viscoelastic and highly viscoelastic films, and formulae accurate to first order are given for films of intermediate viscoelasticity."

Rare Earth Metal - Metal Halide Systems, Lanthanum, Cerium, and Praseodymium Bromides (open access)

Rare Earth Metal - Metal Halide Systems, Lanthanum, Cerium, and Praseodymium Bromides

Technical report. From Abstract : "The MBr3 + M phase diagrams for lanthanum, cerium, and praseodymium are presented. Lanthanum and cerium exhibit simple solutions of metal, with 14 and 12 mole % dissolved at eutectic temperatures of 728 and 687°, respectively. The compound PrBr2.38 is found, melting incongruently to a solution of 16% Pr in PRBr3 and Pr(s) at 601°. For praseodymium the cryoscopic behavior of dilute solutions of metal is consistent with the primary formation of the Pr2+ solute. But with lanthanum and cerium the results are anomalous, as the cryoscopic analyses indicate 1.6-1.7 and 2.0 new particles (cation basis) per metal dissolved instead of ~3."

Reactions in Tracks of High Energy Particles

Abstract. An a priori calculation of the radiolysis of oxygen gas in the pressure ; range 10-3 to 100 atm has been made. In the low background region (1- 100 atm) all track effects have been considered. The calculated G(O3) values seem to be in reasonable agreement with experiment if only one excited oxygen molecule is initially formed per ion pair. Effects of pressure, LET and dose rate have been discussed. The radiation-induced chain decomposition of O3 has not been considered.
