Spectral Radiance Between 0.42 mu and 1.1 mu of Rubidium and Cesium Vapor Arc Lamps as Function of Power Input and
Abstract:
The spectral radiance between 0.42 mu. and 1.1 mu of rubidium and cesium vapor arc lamps was measured for various input powers and vapor pressures. A strong resonance broadening of the resonance lines was observed at high pressures. A strong continuum in the visible is tentatively attributed to Stark broadening of the overlapping lines of the higher order numbers of the 6p-nd and 5d-nf series and to the related series border continua. Data are given for total radiance (0.42-1.1 mu) as function of pressure, for the efficiency vs power input, and the lamp voltage and current.
