Quasi-Elastic Light Scattering Diagnostics for a High Voltage Spark Discharge
Quasi-elastic light scattering was used as a diagnostic probe into analyte material transport processes in a unipolar, positionally stable, high voltage spark discharge. The material transport by particulate intermediates was studied. Instrumentation was constructed to allow spatially-, …

Theory and application of quasi-elastic equations in terrain-folowing coordinates based on the full pressure field
The thesis reports on the development of a new quasi-elastic nonhydrostatic model, cast in a terrain-following coordinate based on the full pressure field. The equations used are the ƒã coordinate by White (1989). The equations are filtered of vertically propagating acoustic waves. However, since …

PRECISION MEASUREMENT OF QUASI-ELASTIC TRANSVERSE AND LONGITUDINAL RESPONSE FUNCTIONS IN THE RANGE 0.55 GeV/cj <q <1.0 GeV/c
The Coulomb Sum is defined by the quasi-elastic nucleon knock-out process and it is the integration of the longitudinal response function over the energy loss of the incident electron. The Coulomb sum goes to the total charge at large q. The existing measurements of the Coulomb Sum Rule show …
