Production of Neutral Photopions as a Function of Atomic Weight (open access)

Production of Neutral Photopions as a Function of Atomic Weight

Thesis discussing the relative yield of neutral pions from elements in a reaction "as a function of the quantum-limit energy (the maximum energy of the quanta in the bremsstrahlung beam) of the Berkeley synchrotron." Interpretation of the results leads to values for the mean free path for absorption of the neutral pions in nuclear matter.

Analysis of the Interaction of 300-Mev Neutrons with Xenon (open access)

Analysis of the Interaction of 300-Mev Neutrons with Xenon

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. Interpretations of results are given.

Alpha-Decay Studies in the Heavy-Element Region (open access)

Alpha-Decay Studies in the Heavy-Element Region

Using primarily a 75-cm radius of curvature 60 deg symmetrical electromagnetic analyzer, a study of the complexity of the following alpha spectra was made: Es/sup 253/, Cf/sup 246/, Cm/sup 244/, Am/sup 243/, Pu/sup 236,242/, Pa/sup 231/ , Th/sup 227,230/, Ac/sup 225/, At/sup 209/ and Po/sup 206/. An investigation of the gamma rays associated with the following isotopes was also madei /sup 236/, and Pa/sup 231/. Decay schemes have been suggested for most of the isotopes included in this study. Those for the even-even isotopes were found to conform well with the previously existing systematics for that group of nuclides. Many of the decay features of the odd-mass isotopes seemed to conform well with presently expanding theories. (auth)

Electric Conduction in an Oil-Pumped Vacuum System (open access)

Electric Conduction in an Oil-Pumped Vacuum System

The leakage of electricity aoross a vacuum space in an electrostatic generator which employs a mixture of Sr/sup 90/ and Y/sup 90/ as the source of charging current was investigated. The vacuum is obtained by means of an oil pump. The leakage was shown to consist of a flow of positive and negative particles between the anode and the cathode. The positive particles were found to be primarily organic ions produced in a layer of oil on the surface of the anode. The negative particles were shown to be mostly electrons. Yields of secondary negative particles and secondary positive particles produced by average positive particles in the energy range from 50 to 200 kev were measured. Yields were found to be dependent on the nature of the target material as well as on the energy of the incident ion. A mass spectrometer was employed to study the nature of the positive ions. Most of these were charged fragments of organic molecules. Neutral particles were attributed to dissociation of a portion of positive ions during their flight from the anode to cathode. Electrons, most of which originate at the beta source, are presumed to be the agent for positive ion production. …

A Survey of the Medical Services in the Texas Prison System (open access)

A Survey of the Medical Services in the Texas Prison System

The purpose of this research paper was to conduct a hospital management survey of the administration of medical services for prison inmates within the Texas Prison system. This type of survey has not been conducted within the medical services of the Texas Prison System in the past by any individual, or public or private group. Specific purposes were to appraise certain major areas in this system, to compare these findings with authoritative survey criteria, and to make recommendations based on the findings of the investigation.

Development of the Punched Card Registration System at North Texas State College

This study presents a history of the development and implementation of a punched card registration system in North Texas State College. The study also covers planning stages of registration materials, and a description of the various stages and processes involved in a typical semester from pre-registration preparations through posting the student's grades to the permanent record. To help fill the need for ready reference to methods used in various institutions across the nation, this study will present a history of the development and implementation of a punched card registration system in North Texas State College, with emphasis placed upon those areas of probable major interest to other colleges faced with a similar problem. The study will cover planning stages of registration materials, and will then present a a description of the various stages and processes involved in a typical semester from pre-registration preparations through posting the student's grades to the permanent record.
