Results from the fly’s eye experiment
(The American Institute of Physics, 1995-07-10)
We report recently analyzed results on the energy spectrum, and composition of cosmic rays above 0.3 EeV. We observe a break in the spectrum at 3 EeV and a changing composition. The results can be explained by a simple two ...
Introduction to “tsunamis: 1992–94”
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1995-09)
Analysis of seismological and tsunami data from the 1993 Guam earthquake
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1995-09)
The fault parameters of the Guam earthquake of August 8, 1993 are estimated from seismological analyses, and the possibility of identifying the actual fault plane from tsunami waveforms is tested. The Centroid Moment Tensor ...
Pulsed terahertz‐beam spectroscopy as a probe of the thermal and quantum response of YBa2Cu3O7−δ superfluid
(The American Institute of Physics, 1995-11-13)
Pulsed terahertz spectroscopy is used to determine the superfluid response of a YBa2Cu3O7−δ film under both thermal and optical stimulation. The coherent, time‐domain technique is used in a novel configuration to directly ...
Canonical partition function for the hydrogen atom via the Coulomb propagator
(The American Institute of Physics, 1995-03)
The electronic partition function for the hydrogen atom is derived by integration over the recently‐available Coulomb propagator. This provides a resolution to an old paradox in statistical mechanics: the apparent divergence ...
Simulation of dynamic fracture of an impact-loaded brittle solid: microcracked and polycrystalline solids
(IOP Publishing Ltd, 1995-09-01)
A modified molecular dynamics method is introduced to describe the dynamic fracture and damage accumulation of impact-loaded brittle solids with realistic microstructural features. We examine the influence of pre-existing ...
Spatial and spectral characteristics of spontaneous emission from semiconductor quantum wells in microscopic cylindrical cavities
(The American Institute of Physics, 1995-12-25)
The spontaneous emission rate from an In0.2Ga0.8As quantum well in a cylindrical dielectric cavity with submicron radii and without mirrors in the emission plane is calculated based on a rigorous description of the cavity ...
The microwave spectrum and structure of the methanol⋅SO2 complex
(The American Institute of Physics, 1995-10-15)
The rotational spectra of nine isotopomers of the methanol⋅sulfur dioxide van der Waals complex were observed with a pulsed molecular beam Fourier transform microwave spectrometer. Each rotational transition is split into ...
