Coulomb focusing and path'' interference of autoionizing electrons produced in 10 keV He sup + + He collisions
Autoionizing electrons emitted following low energy ion-atom collisions may scatter significantly from the receding spectator ion's attractive Coulomb field. In such cases the observed electron intensity is focused'' in the direction of the scattering ion as a result of the effective compression of the emission solid angle. In addition, interference may occur between trajectories, corresponding to electrons scattering around opposite sides of the ion, which lead to the same final laboratory electron energy and emission angle. This Coulomb path'' interference mechanism manifests itself in the uncharacteristically rapid angular dependence of the He target 2s{sup 2} {sup 1}S autoionizing state measured near 0{degree} following low energy He{sup +} + He collisions. A classical trajectory model for Coulomb focusing is presented and a semi-classical approximation is used to model the Coulomb path'' interference mechanism. In this description we account for the evolution of the phase of the autoionizing state until its decay and the path dependence of the amplitude of the emitted electron following decay of the autoionizing state. Calculated model lineshapes, which include contributions from adjacent overlapping resonances, reproduce quite well the angular dependence observed in the data near 0{degree}. 14 refs., 7 figs.

Development of Rotating Shadowband Spectral Radiometers and GCM Radiation Code Test Data Sets in Support of ARM. Technical Progress Report, September 15, 1990--September 14, 1991
Three separate tasks are included in the first year of the project. Two involve assembling data sets useful for testing radiation models in global climate modeling (GCM) codes, and the third is concerned with the development of advance instrumentation for performing accurate spectral radiation measurements. Task 1: Three existing data sets have been merged for two locations, one in the wet northeastern US and a second in the dry western US. The data sets are meteorological data from the WBAN network, upper air data from the NCDC, and high quality solar radiation measurements from Albany, New York and Golden, Colorado. These represent test data sets for those modelers developing radiation codes for the GCM models. Task 2: Existing data are not quite adequate from a modeler`s perspective without downwelling infrared data and surface albedo, or reflectance, data. Before the deployment of the first CART site in ARM the authors are establishing this more complete set of radiation measurements at the Albany site to be operational only until CART is operational. The authors will have the site running by April 1991, which will provide about one year`s data from this location. They will coordinate their measurements with satellite overpasses, and, to …

Modeling of large aperture third harmonic frequency conversion of high power Nd:glass laser systems
To provide high-energy, high-power beams at short wavelengths for inertial-confinement-fusion experiments, we routinely convert the 1.053-{mu}m output of the Nova, Nd:phosphate-glass, laser system to its third-harmonic wavelength. We describe performance and conversion efficiency modeling of the 3 {times} 3 arrays potassium-dihydrogen-phosphate crystal plates used for type II/type II phase-matched harmonic conversion of Nova 0.74-m diameter beams, and an alternate type I/type II phase-matching configuration that improves the third-harmonic conversion efficiency. These arrays provide energy conversion of up to 65% and intensity conversion to 70%. 19 refs., 11 figs.

Molecular biological enhancement of coal desulfurization. Eleventh quarterly technical progress report
The objective of this project is to produce one or more microorganisms capable of removing the organic and inorganic sulfur in coal. The original specific technical objectives of the project were to: clone and characterize the genes encoding the enzymes of the ``4S`` pathway (sulfoxide/sulfone/sulfonate/sulfate) for release of organic sulfur from coal; return multiple copies of genes to the original host to enhance the biodesulfurization activity of the organism; transfer this pathway into a fast-growing chemolithotrophic bacterium; conduct a batch-mode optimization/analysis of scale-up variables.
