OCTOBER 1965 STATUS REPORT,
Abstract
Measurements of the line shapes of the D lines of the atomic fluorescence of the sodium iodide dissociated by the ultraviolet light were made. The reduction of intensity of light that was passed through an extremely narrow band pass instrument made it necessary to cool the phototube to reduce the dark current noise in the cases where the exciting ultraviolet light was also highly attenuated by the polarizing disc. The Doppler widths were somewhat narrower than expected. Some remaining uncertainties in the effective resolving power at the time of each measurements must be eliminated (by calibration against the standard Hg 198 lamp immediately before and after each measurement) before a precise quantitative determination of the Doppler widths for the D lines can be achieved. Both lines appear to be equally broadened. (Author)
