Diosmacycloalkanes as models for the formation of hydrocarbons from surface methylenes

Description: We are making progress on our investigation of the mechanism of olefin exchange with Os{sub 2}(C{sub 2}H{sub 4})(CO){sub 8}. We are probing this system by kinetic study of the reaction of Os{sub 2}(C{sub 2}H{sub 4})(CO){sub 8} with butyl acrylate (BA) under various pressures of ethylene.

An Application of the Concepts of Particle Packing to the Consolication of Silicon Carbide Powders

Description: From introduction: Silicon carbide is being considered as a basis material for nonmetallic fuel elements because of its high thermal conductivity, low nuclear cross section, high resistance to thermal rupture, and high degree of stability at high temperature in air. A requirement of the fuel elements is that they be thin and have as low porosity as possible. One shape of element under consideration is 0.050 to 0.070 inch thick by a few inches in width and breadth.

Preliminary Report on Existing Active Particle Hazard-200 Areas

Description: "Recent surveys by the Health Instrument Section have disclosed the presence of many small radioactive spots on ground surfaces in the T and B plant areas. Investigation has shown that representative samples of the spots when mechanically separated invariably end in a single radioactive particle."

Solar wind iron abundance variations at solar wind speeds > 600 km s/sup -1/, 1972 to 1976

Description: We have analyzed the Fe/H ratios in the peaks of high speed streams (HSS) during the decline of Solar Cycle 20 and the following minimum (October 1972 to December 1976). We utilized the response of the 50 to 200 keV ion channel of the APL/JHU energetic particle experiment (EPE) onIMP-7 and 8 to solar wind iron ions at high solar wind speeds (V greater than or equal to 600 km sec/sup -1/), and compared our Fe measurements with solar wind H and He parameters from the Los Alamos National Laborator… more

Ornithogalum Virens as a Plant Assay for Beta and Gamma Radiation Effects

Description: The purpose of this study was to determine if the monocotyledonous angiosperm, Ornithogalum virens (Quintanilha and Cabral, 1947), could be used in such a biological assay system. After exposing O. virens plants to acute (/sup 60/Co) and chronic (/sup 137/Cs) gamma radiation and internal beta radiation (/sup 32/P), lethality (LD/sub 50/, LD/sub 100/), growth inhibition, and chromosome aberrations were investigated. The LD/sub 50/ and LD/sub 100/ for acute gamma radiation were estimated to be be… more

Neutron Production by High-Energy Particles

Description: Abstract: "From neutron-yield measurements made with a MnSO4 detecting solution, the average number of neutrons produced per inelastic event is determined for a series of elements from lithium to uranium for 340-Mev protons, 190-and 315-Mev deuterons, 490-Mev He3 ions, and 90- and 160-Mev neutrons. The results are analyzed in an attempt to understand the total yield measurements for thick targets and to explain the variation of yield with the atomic number of the target."

Machine Calculations for the Analysis of the Plane Immobilized Plasma by Trajectories

Description: Abstract: "The analysis of an immobilized plasma by trajectories for the Cartesian case has been adapted to machine calculation and the results of such calculations are described. Their most surprising features is the thinness of the transition layer between a vacuum and a uniform plasma, which is possible without assuming too extreme physical circumstances."

Gravitational-Electromagnetic Torus Models of the Elementary Particles

Description: Abstract: "A torus model of the elementary particles is suggested in which the electron and proton are made stable by gravitational forces derived from the electromagnetic field. It is suggested that the gravitational forces for the unstable particles, presumably the mesons, are not sufficient to keep the torus from expanding in the direction of its large radius. Rest energy zero can be achieved, presumably for photons and neutrons, when the gravitational energy and electromagnetic field energy… more

Studies of relativistic heavy ion collisions. Annual progress report, August 1, 1992--July 31, 1993

Description: With the completion of the experimental runs with the DLS, which included both heavy ion and nucleon projectiles and targets, is being completed the analysis of these high statistics experiments. The Hopkins group has a major responsibility in comparing the experimental results with recently developed simulation codes for a theoretical comparison. The second major activity involves the STAR experiment at RHIC, to continued involvement with simulations and development of prototypes of detector s… more

Fluxes of Tracers in Wind and Water Tunnels

Description: The absorption process of particulate matter at an air-water interface was studied by means of a Monte Carlo Simulation. This absorption process does not appear to be significantly different from similar processes over stationary boundaries. Especially an increased flux toward the boundary as the result of more effective particle removal due to wave action could not be observed. The particular nature of the tracer prevents this from happening.

Final Technical Report, Outstanding Junior Investigator Award for De-fg02-94er40869

Description: This report summarizes the research of the Principal Investigator, his postdoctoral research associates, and his students during the period of the award. The majority of the work concerns the behavior of hadrons containing strange, charm, bottom and top quarks, with a particular focus on the extraction of Cabibbo--Kobayashi--Maskawa matrix elements from experiments performed on such systems.

Capillary discharge extreme ultraviolet lasers. [Colorado State Univ. , Ft. Collins]

Description: The project objective is to explore the generation of soft X-ray laser radiation in a plasma column created by a fast capillary discharge. The proposed capillary lasing scheme offers the potential for compact, simple and efficient soft X-ray laser sources. For this purpose a compact, fast pulse generator which produces 100 kA current pulses with a risetime of 11 ns was constructed. Initial experiments were conducted in evacuated capillaries, in which the plasma is produced by ablation of the ca… more

The Quantum Mechanical Scattering Problem II: Multi-Channel Scattering

Description: "The study of the single channel scattering problem was extended to include the multi-channel case. The scattering problem was formulated in a mathematically rigorous way which reflects the time-independent point of view but is not limited by any dependence on a configuration space representation. Wave operators were defined by an integral representation. When the conditions necessary for the time-dependent formulation are valid these wave operators will be identical to those defined by the asy… more

A Cloud Chamber Study of the Secondary Particles from Locally Produced Penetrating Showers

Description: The present experiment was undertaken as an attempt to throw more light on the decay processes that had been observed prior to the summer of 1952, as well as to investigate any new decay processes that might manifest themselves. The source of high energy primary particles was to be the cosmic ray beam, so a detector of locally produced high energy penetration showers was used. In order to be able to detect effectively low energy photons and low energy secondaries from particles reaching the end… more

Lawrence Berkeley Laboratory Accelerator & Fusion Research Division Annual Report: 1982

Description: This report covers the activities of LBL's Accelerator and Fusion Research Division (AFRD) during 1982. In nuclear physics, the Uranium Beams Improvement Project was concluded early in the year, and experimentation to exploit the new capabilities began in earnest. Technical improvement of the Bevalac during the year centered on a heavy-ion radiofrequency quadrupole (RFQ) as part of the local injector upgrade, and we collaborated in studies of high-energy heavy-ion collision facilities. The Divi… more
