A technique for measuring internal friction in vibrating reeds

Creator:: Jewell, Wm. R. (William Ray)
Resource Type:: Dissertation

De-Haas van-Alphen effect in the quantum limit

Creator:: Karniewicz, Joseph J.
Abstract:: In this work we apply the finite temperature formulation of quantum statistical mechanics to an analysis of the de Haas-van Alphen effect in the quantum limit. A new expression is derived for the differential magnetic susceptibility which clearly shows the individual contributions of zero-temperature and non-zero temperature terms. Interactions have...

Measurements of atmospheric sodium abundance by direct absorption of sunlight

Creator:: El Tayyan, Ahmed Asad
Abstract:: The atmospheric sodium daytime abundance was measured for Corvallis, Oregon, using direct absorption of sunlight by atmospheric sodium atoms, as observed with an optical waveguide spectrum analyzer. The disadvantage of the spectrum analyzer is that it can't resolve the sodium D-lines (Its resolving power is 0.5 nm, which is approximately...

Incorporation of hyperfine probes into the thin-film superconductor YBa₂Cu₃O₇₋δ during deposition

Creator:: Tom, D. W., Platzer, R., Gardner, John A., and Tate, Janet
Abstract:: Radioactive In has been incorporated into oriented thin films of YBa₂Cu₃O₇₋δ during a thermal coevaporation process. The hyperfme technique of perturbed γγ-angular correlation spectroscopy shows that 60% of the indium substitutes at a single site in the superconductor. We obtain spectra with reasonable statistics from 2 mCi of starting material,...

Pion content in nucleon using finite renormalization scheme with spectral amplitude separation of ghosts

Creator:: Symmes, Jonathan P.
Abstract:: We develop a technique to express the nucleon pole strength and bare mass in terms of renormalized quantities. Starting from a general unrenormalized self energy we determine the bare mass and the pole strength. For determining the pion content of the nucleon we discuss the leading renormalization loop. We relate...

Scaling of thin-film Nd₁.₈₅Ce₀.₁₅CuO[subscript 4-y] resistivity-current isotherms at low fields: Implications for vortex phase transitions and universality

Creator:: Roberts, J. M., Brown, Brandon, Tate, Janet, Xi, X. X., and Mao, S. N.
Abstract:: We have investigated a second-order phase transition of the vortex lattice in thin-film Nd₁.₈₅Ce₀.₁₅CuO[subscript 4-y] from 1 mT to 1 T applied magnetic fields. The dc resistivity-current density data for each field exhibit critical scaling consistent with a second-order vortex-liquid to vortex-solid phase transition. The high-field data support the vortex-glass...

Thermal neutron capture cross sections of 68Ge and 148Gd

Creator:: Rios, Maribel Gómez
Resource Type:: Masters Thesis

Relation between bandstructure and magnetocrystalline anisotropy : iron and nickel

Creator:: Wang, Haiyan
Abstract:: A large amount of research has been done in which the magnetocrystalline anisotropy energy for fcc Ni and bcc Fe was calculated based on the electronic structure of these elements. Unfortunately; the results of these studies don't agree with each other and also differ from the experimental observation. In a...

Flux-limited diffusion theory for spatially discretized equations : a discretized derivation of Levermore-Pomraning FLDT

Creator:: Laubsch, Bertrand
Abstract:: Spatially discretized diffusion approximation equations are derived directly from spatially discretized radiation transport equations in 1-D slab geometry. Derivations for isotropic diffusion theory (IDT) and Levermore-Pomraning's flux-limited diffusion theory (FLDT) are applied to lumped linear discontinuous (LLD) transport equations. We find that the (energy density) solution is continuous across the...

The fabrication of fiber Bragg gratings

Creator:: Stump, Kurt
Abstract:: Fiber Bragg gratings have become an important element in the fields of telecommunications and fiber optical sensing. Their small size, light weight and high tunability have made them ideal for many unique applications. In this paper the fabrication of these devices is investigated. Following a review of current literature and...
