X-ray study of an isobranched lecithin

Creator:: Herpe, Joachim
Abstract:: Lipids, especially phospholipids, are very common but important molecules found in cells and animal tissue, performing many biological functions, particularly in membranes. Lipids, when mixed with water, spontaneously form ordered systems, such as micelles, vesicles and multibilayers. The size of these systems and their degree of ordering depend on the...

Monte Carlo Radiation Transfer Simulations of Gamma Ray Burst Prompt Emission

Creator:: Parsotan, Tyler M.
Abstract:: Gamma Ray Bursts (GRBs) are the most energetic explosions in the Universe, producing up to $\sim10^{53}$ ergs of energy in the first few seconds of their emission -- the so-called prompt phase that is dominated by high energy X-ray and $\gamma$-ray photons. The very large luminosities released in these events...

Gamma- and beta-ray spectroscopy studies of the radioactive decay of Mn-51 to Cr-51

Creator:: Glibert, Kenneth Malcolm
Abstract:: The decay scheme of Mn⁵¹ has been investigated using gamma-ray and beta-ray scintillation spectrometers and a fast coincidence spectrometer. A half-life value of 46.5 ± 0.2 minutes was determined for Mn⁵¹ which decays predominantly to the ground state of Cr⁵¹ by the emission of positons with an experimentally measured end-point...

Growth and characterization of the p-type semiconductors SnS and BiCuOSe

Creator:: Francis, Jason
Abstract:: BiCuOSe and SnS are layered, moderate band gap (ε[subscript G] ≈ 1 eV) semiconductors that exhibit intrinsic p type conductivity. Doping of BiCuOSe with Ca results in a slight expansion of the lattice and an increase of the hole concentration from 10¹⁸ cm⁻³ to greater than 10²⁰ cm⁻³. The large...

Dust in the wind : the role of recent mass loss in long gamma-ray bursts

Creator:: Margutti, R., Guidorzi, C., Lazzati, D., Milisavljevic, D., Kamble, A., Laksar, T., Parrent, J., Gehrels, N. C., and Soderberg, A. M.
Abstract:: We study the late-time (t > 0.5 days) X-ray afterglows of nearby (z < 0.5) long gamma-ray bursts (GRBs) with Swift and identify a population of explosions with slowly decaying, super-soft (photon index Γx > 3) X-ray emission that is inconsistent with forward shock synchrotron radiation associated with the afterglow....

Gamma-gamma directional correlation study of barium-134

Creator:: Coleman, Lamar William
Abstract:: Gamma-gamma directional correlations were measured in Ba¹³⁴ at ten angles between 90 degrees and 180 degrees in ten degree increments using a scintillation spectrometer. The spectrometer which used NaI crystals, differential energy selection, and standard coincidence techniques was tested by measuring the directional correlation of the two cascade gamma rays...
