INVESTIGATION OF THE EFFECT OF GAS COLLISIONS UPON THE DOPPLER BREADTH OF SPECTRAL LINES Radio Frequency Transitions between Hyperfine Levels of Atomic Hydrogen

摘要

Various measurements of pulsed sideband power were completed. Work has been suspanded on the hydrogen resonance in favor of the apparently more feasible rubidium resonance.nWork on an optically pumped frequency standard has begun. Rubidium 87 has been chosen because of certain advantages in all its general properties. Ways of obtaining self-maintained oscillations of such a system have been considered. A stabilized frequency soures to study the system and to be used as a local oscillator is the first project.
