Decay Study of Pb202m
(1970)The decay of 3.62 hour Pb202m has been studied using high-resolution y-ray spectroscopy in an effort to elucidate its nuclear structure. Singles and y-y coincidence measurements were taken with the result that the previously ... -
Decomposition of Virus Normal Modes into Spherical Harmonics An Exploration of Symmetry Adapted Functions (SAFs)
(2020-02-13)The normal modes for viruses, in which all of its atoms are oscillating at the same frequency, can be thought of as a very complicated system of masses and springs. Each atom has its own mass, and the bonds between atoms ... -
Delphi - A General Purpose Research Data Editing Language
(1980)Data editing is the process of checking data for possible inaccuracies. This paper describes possible types of data edits, discusses the underlying theory . used in generating a "complete set of edits" and the finding and ... -
Design and Construciton of a Photodiode-Based Passive Spectrometer
(2005)The use of passive spectroscopy to determine electron temperatures is well documented and has the important benefit of being noninvasive. The use of line intensities in particular is important because other spectrographic ... -
The Design and Construction of a Helium Dewar System
(1971)THE PURPOSE OF THIS PAPER IS TO PRESENT ASPECTS OF THE DESIGN AND CONSTRUCTION OF A HELIUM DEWAR SYSTEM. AN EXTENSIVE BACKGROUND SECTION PRESENTS THE READER WITH A FOUNDATION IN THE PROBLEMS OF DEWAR SYSTEM DESIGN. THE ... -
The Design and Construction of an Automatic Interferometer
(1970)The idea of building an automatic interferometer :. stemmed from a specific problem. During the generation of complex optical surfaces there occurs a certain stage in the process of fine grinding at which the use of ... -
Design and construction of Atmospheric Telemetering Devices
(1977)The purpose of this project was to build and fly a radio-controlled model airplane, which would be used to carry radio telemetering instruments. These instruments would measure temperature, pressure, and wind speed in the ... -
Designs for Medical Physics Laboratory Experiments
(1977)The purpose of this project is to develop laboratory experiments for the Medical Physics (Physics 52) class of Kalamazoo College. Since this is a non-majors course, it is desirable to find experiments which not only ... -
Detecting the Onset of Swelling in High Temperature Ceramic BiSrCaCuO Superconductors during Sintering
(1993)Superconductors are electrical conductors that have the property of carrying large amounts of current at very low temperatures (around 5-10K). These materials must undergo an intensive heating process called sintering that ... -
The Detection of Crystal Field Splitting in Eu(III) with a Narrow-band Tunable Cw Dye Laser
(1979)The development of lasers which can be tuned over a wide range, typically 50-100nm, with the output wavelength confined to a narrow-band has made it possible to increase both the sensitivity and resolution of conventional ... -
Determinant Quantum Monte Carlo simulations of charge density waves in the Holstein model with a double well potential
(2022-11-01)This work is concerned with transitions to the ordered charge density wave (CDW) phase. CDWs are well studied, but there is still more to explore, especially as they relate to superconductivity. In some instances, CDWs are ... -
Determination of Charge of Lambda Hyperfragments
(1965)The present method gives results that are at least acceptable. There are other methods that are better, chiefly: variations on presentation of data, but these are restricted in some way. The results from this method ... -
Determination of Detection Efficiencies of CsI Photodiode and Microchannel Plate Detectors
(1989)We have measured the detection efficiencies of a CsI photodiode (Si02 windowed) and a microchannel plate detector (MCP) with an opaque CsI photocathode at 1850 A. Also, a detection efficiency curve was measured for a ... -
Determination of Elastic Constants through Analysis of Ultrasonic Elastic Wave Velocities
(1982)This Senior Independent Project is a Physics Research Project carried out in the physics department at Wayne State University. This project is in the area of solid state physics, and deals. specifically with the behavior ... -
Determination of Magnetic Susceptibilities Using Nuclear Magnetic Resonance
(1967)Since its simultaneous discovery in 1945 by Felix Bloch of Stanford and Edward Purcell of Harvard, nuclear magnetic resonance (NMR) has become a research technique of great importance, especially in the areas of investigating ... -
Determination of Sound Velocities in Liquids Using Light Diffraction of Ultrasonic Waves
(1965)Previous to the writing of this paper, Paul A. McIntosh, a 1964 Kalamazoo College graduate, examined diffraction of light by ultrasonic waves. More specifically, he derived the equation for the wave1ength of sound in ... -
A Determination of the Response Characteristics of Underwater Electrostatic Transducers
(1964)High-frequency electrostatic transducers have recently found many applications as transmitters and receivers of ultrasonic waves in gases, in a frequency range extending to one megacycle. The flat response over wide ...
