Stark-broadening measurements of singly ionized xenon

Abstract
Linewidths of four visible Xe II lines are measured in a conventional shock tube. The Stark effect is the dominant broadening mechanism. Electron densities vary widely over the range (1-15) × 1016 cm3, but temperatures remain in the narrow range 7800-8400 K. Great care has been taken to minimize possible systematic errors in the electron-density and optical-depth measurements.
