INVESTIGATION OF THE EFFECT OF GAS COLLISIONS UPON THE DOPPLER BREADTH OF SPECIAL LINES Radio Frequency Transitions Between Hyperfine Levels of Atomic Hydrogen 2nd Quarterly Report (September 15, 1952 through December 15, 1952)

摘要

Continuing the work of the first quarter, detailed calculations on signal and noise powers with various detection schemes have been made. Additional apparatus has been constructed and tested, notably a high-level pulser and a coincidence gating oirouit. Preliminary attempts to find the desired resonance were unsuccessful.
