K-Shell Ionization Cross Sections of Selected Elements from Fe to As for Proton Bombardment from 0.5 to 2.0 MeV

Description: The problem with which this investigation is concerned is that of making experimental measurements of proton-induced K-shell x-ray production cross sections and to study the dependence of these cross sections upon the energy of the incident proton. The measurements were made by detection of the characteristic x-rays emitted as a consequence of the ionization of the K-shell of the atom. The method for relating this characteristic x-ray emission to the x-ray production cross section is discussed … more

Keyboard Tablatures of the Mid-Seventeenth Century in the Royal Library, Copenhagen: Edition and Commentary

Description: In the history of seventeenth-century European music the court of Christian IV (r. 1588-1648) occupies a position of prominence. Christian, eager for fame as a patron of the arts, drew to Denmark many of the musical giants of the age, among them the lutenist John Dowland and the composer Heinrich Schltz. Sadly, except for financial records and occasional letters still in the archives, few traces remain of these brilliant years in Denmark. The music composed and played during this half century h… more

Established Fabric Techniques Used to Create Motorized Forms

Description: The ancient artist's influences can still be felt in today's craftsmen. For example, the contemporary weaver Sheila Hick's prayer rugs are an assimulation of the textile techniques of ancient Peru, Persia, and India, and the macramed forms of the contemporary Spanish artist, Aurelis Munoz, are suggestive of the woven huts of many primitive cultures. Because of this influence upon the current investigation, the evolvement of weaving and its techniques, as well as the three-dimensional techniques… more

High-resolution studies of beta-delayed proton emission in light nuclei

Description: Thesis. Identified protons were observed following beta decay of the precursor nuclei /sup 21/Mg, /sup 25/Si, /sup 37/Ca, /sup 40/Sc, /sup 41/Ti, and / sup 23/Al. These measurements spanned a proton energy range from 600 keV to 8.5 MeV, and included all significant particle decays of these nuclei. A helium-jet transport system was developed and used with various DELTA E - E counter telescopes to obtain high-resolution, lowbackground spectra. These data perrmitted accurate location of proton unb… more
