Franck Condon Factors And R-Centeroids For Six Diatomic Molecules, Patricia M. Fazio
Franck Condon Factors And R-Centeroids For Six Diatomic Molecules, Patricia M. Fazio
Physics Theses & Dissertations
The Franck Condon factor is defined as the square of the overlap integral and is so named because of its ties with the Franck Condon Principle. The r-centroid is the internuclear separation associated with the electronic transition of the diatomic molecule. The physical meaning of these integrals is discussed. Two methods for construction of the wavefunctions are presented. Both methods employ the Morse Potential Energy function. The first method calculates the integrals using the analytic wavefunction of Morse and the second method has numerically constructed wavefunct!ons. The twelve transitions and six diatomic molecules studied include; B 2Σ+ to X …

The Effects Of Proton Irradiation On The Absorption Of Multi Component Glasses, Marcia Frances Bartusiak
Physics Theses & Dissertations
Three Schott glasses typically used in space technology - LaK 21, KzFS N4, and LF 5 -- were irradiated with 85 MeV protons. Induced absorption spectra were determined for each glass after varying fluences of radiation. It was found that the spectra for each glass can be fitted with three Gaussian shaped bands in the near ultraviolet-visible region, while a fourth Gaussian characterizes the absorption edge. For doses up to 107 rads, the dependence of the induced absorption a on total dose is accurately described by the saturating exponential function a(Φ)= as (1 - e--b Φ ) …
