INVESTIGATION OF THE EFFECT- OF GAS COLLISIONS AND OPTICAL PUMPING CM THE BREADTH OF SPECTRAL LINES Microwave Atomic Oscillator Using the Hyperfine Transition of Rb 87 7th Quarterly Report (March 1, 1957 - May 30, 1957)

摘要

The work during this quarter (and including June l – July 15) has brought the microwave detection method of observing Doppler reduced and optically pumped Pb87 resonance lines to completion. The results show that the gas cell technique can be made to work as well as atomic beams, but with greater simplicity and several other advantages. The pressure shift has been more carefully measured and found to be much less than previously estimated.
