Support and Extension of the Rotational Model of Thin Film Magnetization
This paper describes the magnetic behavior of some thin permalloy films in terms of the rotational model of Stoner and Wohlfarth. Experimental evidence is shown for the existence of a single domain whose orien...

Electron Transport Phenomena and Oscillatory Behavior in the Lattice Conductivity of an Antimony Single Crystal in a Magnetic Field at Low Temperature
With the magnetic field parallel to the trigonal direction, the experimental coefficients of the transport effects have been measured in the basal plane of an antimony crystal, i.e., in a transverse field. The...

Standards and Correction Procedures in Electron-Probe Analysis of Rock-Forming Minerals
A large proportion of the substances which fall under the heading of rock-forming minerals consist of silicates and oxides incorporating elements from Z = 11 (Na) to Z = 28 (Ni) in addition to oxygen and hydrogen...

Observation of soft X-ray emission from a region near Per X-1
Soft X-ray emission from the X-ray source Per X-1 was observed in the 0.4–2 keV energy interval from a rocket borne X-ray detector. Spectral analysis of the data indicates that in the 0.4–2 keV band the X-ray ...

Phonon reflection at a cleaved sodium fluoride-helium film interface
High-frequency phonons (hω/k B≳10 K) have been reflected on the solid side of a sodium fluoride-helium-4 interface. The reflectivity was measured as a function of helium film thickness and it was found that most ...

Energy transfer from solids to helium vapor by the desorption of surface-bound atoms
Energy transfer from solid to helium vapor by desorption of surface-bound helium atoms is examined. The ideas presented give a good qualitative explanation of recent phonon reflection data, and preliminary num...

General-altitude transformations between geocentric and geodetic coordinates
Formulas for the general-altitude (height above the ellipsoid) transformation from geocentric to geodetic coordinates and vice versa are derived. The set of four formulas is expressed in each of two useful for...

Molecular absorption of infrared laser radiation in the natural atmosphere
This paper discusses the information available concerning atmospheric molecular absorption of radiation in the 1 to 25μm range. Particular attention is given to the high spectral resolution requirements for predi...

OSO-8 X-Ray Polarimeter and Bragg Crystal Spectrometer Observations
The OSO-8 satellite contains a focusing mosaic graphite crystal X-ray polarimeter that is oriented along the spin axis of the wheel section of the satellite. The polarimeter operates at 2.6 and 5.2 keV. Polari...

Photovoltaic and Photoconductive Infrared Detectors
Photovoltaic and photoconductive effects in solids are widely used for detecting infrared radiation. These detectors offer very high detectivities, although they must often be cooled to achieve such performanc...

The Bight of Abaco Pressure Experiment
In November-December of 1974, we conducted a joint experiment to investigate microscale air pressure fluctuations above surface gravity waves. The primary objective of this experiment was to study the vertical...

Silicon X-ray line emission from solar flares and active regions
New observations of solar flare and active region X-ray spectra obtained with the Columbia University instrument on OSO-8 are presented and discussed. The high sensitivity of the graphite crystal panel has all...

Anomalous pressure dependences of the superconducting transition temperature of dilute alloys of LaSn3 containing light rare earth impurities
The initial depressions of the superconducting transition temperature T c of LaSn3 by rare earth (RE) impurities are known to be anomalous. In an attempt to clarify this behavior, we have measured the pressure de...

Observations of Supernova Remnants in the Large Magellanic Cloud with the Einstein Observatory
As the nearest extragalactic system, the Large Magellanic Cloud (LMC) is destined to play a major role in understanding the X-ray emission from all normal galaxies including our own. Classed as a prototype Sb(...

The Hall Effect in Heavily Doped Semiconductors
The properties of the Hall effect in relatively pure, lightly-doped semiconductors are now generally well understood.1 However, the Hall effect and mobility in heavily-doped semiconductors, which have metal-like ...

Atmospheric and Watershed Inputs of Mercury to Cranberry Lake, St. Lawrence County, New York
Cranberry Lake is a large (28.2 km2) reservoir located in the northwestern Adirondack Mountains in New York State. The area surrounding the lake is primarily wilderness with no major industry. In 1969, fish colle...

The Fluid Mechanical Problem of Fjord Circulations
There are too many theoretical aspects of fluid mechanical research on fjords and estuaries to treat all of them in a single paper even if, contrary to present circumstances, the author could claim overall com...
