Sweeping of the Jovian resonances and the evolution of the asteroids
Author(s): Torbett, M.; Smoluchowski, R.
Abstract: During the formation of the solar system the variation of the gravitational field produced by removal of a nebula with its moderately massive accretion disk led to sweeping of the Jovian commensurability resonances through ...

Vibration-rotation double resonance effects in symmetrical top molecules.
Author(s): Marantz, H.; Frenkel, L.; Sullivan, T.
Abstract: Rotational transitions in symmetrical top molecules in the wavelength regions of 1-3 mm are sufficiently strong to be observed directly on an oscilloscope. Changes in the vibrational level populations induced by laser ...

Power series evaluation of transition and covariance matrices.
Author(s): Bierman, G. J.
Abstract: Reexamination power series solutions to the matrix covariance differential equation and the transition differential equation. Truncation error bounds are derived which are computationally attractive and which extend ...

Snow wetness measurements for melt forecasting
Author(s): Linlor, W. I.; Clapp, F. D.; Meier, M. F.; Smith, J. L.
Abstract: A microwave technique for directly measuring snow pack wetness in remote installations is described. The technique, which uses satellite telemetry for data gathering, is based on the attenuation of a microwave beam in ...

Evidence for the existence of cosmic-ray antiprotons
Author(s): Golden, R. L.; Horan, S.; Mauger, B. G.; Badhwar, G. D.; Lacy, J. L.; Stephens, S. A.; Daniel, R. R.; Zipse, J. E.
Abstract: A search for cosmic-ray antiprotons was recently performed with the use of a balloon-borne superconducting-magnet spectrometer. A total of 46 antiproton candidates were observed in the rigidity interval from 5.6 to 12.5 ...
