[Chemistry Thesis] Part 2: High Intensity Light Sources

Description: A stable carbon arc operated in controlled atmosphere is described. The arc was designed to serve as a light source during lifetime studies of the B/sup 2/ SIGMA state of the CN molecule. The CN radiation from the plasma of the arc was investigated and found to have a brightness temperature of 5500 icient laborato K at lambda 3883 A. This is considerably higher than an estimate of the value required for lifetime measurements. The stability of the carbon arc under various conditions is discussed… more

[Chemistry Thesis] Part 1: The Spectra of Some Aliphatic Aldehydes and Their Monodeutero Derivatives,

Description: BS>An investigation of the infrared and near-ultraviolet spectra of three aliphatic aldchydes and their monodeutero derivatives is described. The infrared spectra of the acetaldehydes (CH/sub 3/CHO and CH/sub 3/CDO) were in agreement with work reported recently. A few new bands are reported and discussed. The infrared spectra of C/sub 2/H/sub 5/CHO, C/sub 2/H/sub 5/CDO, C/ sub 3/H/sub 7/CHO, and C/sub 3/H/sub 7/CDO at 450 to 4000 cm/sup -1/ were observed, and an assignment of the observed bands… more

Spallation-Fission Competition in Neptunium Compound Systems. Decay-Scheme Studies

Description: The results of a radiochemical study of fission and spallation products induced in U/sup 234/, U/sup 235/, and U/sup 236 and spallation products induced in U/sup 238/ by deuterons of less than 24 Mev are presented. The (d,n) reactions are interpreted as the result of direct interactions between the deuteron and the target nuclei, while the (d,n) reactions are thought to be taking place primarily by compound-nucleus mechanisms. A method for predicting the peak values of the cross section for (d,… more

Measurement of Beam Current in the Bevatron by Induced Voltages

Description: The Bevatron uses a system of electrodes through which the internal proton beam passes in order to continuously measure the magnitude and radial position of the beam. The bunched circulating beam induces a periodic voltage on the electrodes. This signal is amplified and displayed on an oscilloscope and also converted to direct current for operation of a recorder. Two types of electrode systems are used. The first is a large hollow box to provide beam magnitude signals for specialized monitoring… more

Analysis of the Interaction of 300-Mev Neutrons with Xenon

Description: Abstract: And investigation of the interactions between 300-Mev neutrons and xenon was made by means of a cloud chamber in a pulsed magnetic field of 21,700 gauss placed in the neutron beam of the 184-inch Berkeley cyclotron. Eighty-seven negative pion events and 257 other stars were analyzed. In addition an experimental check was made on the energy of the incoming neutrons. Classification, identification, and angular and energy distributions of prongs associated with all events are presented. … more

Capacity Factors in the Performance of Perforated Plate Distillation Columns

Description: From abstract: "A study of factors affecting the vapor handling capacity of perforated plate liquid-vapor contacting columns. Vapor phase pressure drop across plates, liquid entrainment upward from plate to plate, and plate stability were investigated as functions of operational and geometric column parameters."
