Book excerpt: Thermoluminescence provides a method for studying properties of those crystalline imperfections which behave as electron traps and recombination centers in wide bandgap materials. This approach, however, has been used relatively little, possibly due to the fact that the shapes and intensities of thermoluminescent glow curves are functions of several experimental parameters and are often complicated by the overlapping of a number of individual glow peaks. In the present work, experimental parameters were isolated and some of their effects on thermoluminescent glow curves were analyzed. This yielded information on activation energies associated with trapping levels, the nature of the kinetics involved in electron transitions, and electron retrapping. A Type II-a diamond, which has a wide distribution of thermoluminescent glow peaks, was used in this work. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Several features of thermoluminescence from chromium-doped lithium germanate were explored. These included: thermoluminescence excitation and emission spectra, thermal activation energies, recombination kinetics, behavior of glow curves as a function of sample temperature-during-excitation, and thermal bleach after excitation. Strong thermoluminescence was obtained by exciting electrons to energies above the U- and Y-absorption bands, and very weak thermoluminescence by exciting to these bands. Thermoluminescence emission occurred in the same wavelength region as fluorescence. Activation energies ranged from 0.17 to 2.3 eV. Thermoluminescence was found to be a sensitive function of temperature-during-excitation; large increases in high-temperature peaks were accompanied by small decreases in low-temperature glow peaks. Thermal bleaching after excitation, however, left high temperature peaks unchanged, while low-temperature peaks were removed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The Wheeler-Feynman absorber theory of radiation is reviewed. A proof is offered to show that a sum of advanced and retarded effects from the absorber can provide the origin of radiative reaction. This proof is different from and perhaps simpler than that of Wheeler and Feynman. From arguments of momentum and energy conservation the necessity of the absorber for the emission of radiation is demonstrated for three cases. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The quantum-mechanical ground-state problem for three identical particles bound by attractive inter-particle potentials is discussed. For this problem it has previously been shown that it is advantageous to write the wave function in a special functional form, form which an integral equation which is equivalent to the Schrodinger equation was derived. In this paper a new method for solving this equation is presented. The method involves an expansion of a two-body problem with a potential of the same shape as the inter-particle potential in the three-body problem, but of enhanced strength.
