Research Investigation Directed Toward Extending the Useful Range of the Electromagnetic Spectrum.
Abstract
Preliminary studies of spin relaxation of optically pumped sodium in xenon gas have shown that Van der Waals NaXe cause a substantial part of the relaxation. The electron-nuclear spin exchange cross section between Na and Xe129 has been measured to be less than ten to the -19th power/sq cm. Calculations and preliminary experiments have shown that radiofrequency spectroscopic studies of the anomalously long lived 5D state of cesium are possible. Further studies of dense alkali vapors have shown that all of the alkali vapors sodium, potassium, rubidium and cesium, have absorption bands in the spectral region between 1 micron and 2.5 micron. The possibility that some of these bands might be useful for the construction of infrared excimer lasers is being investigated.
