Collisional excitation transfer and quenching in Rb(5P)-methane mixtures
M. Alina Gearba, Jeremiah H. Wells, Philip H. Rich +5
We have examined fine-structure mixing between the rubidium and states along with quenching of these states due to collisions with methane gas. Measur…
An Undergraduate Test of Gravitational Time Dilation
Brian Patterson, Mario Serna, Jerry F. Sell +11
Students at Colorado College and cadets at the US Air Force Academy have conducted an experimental test of gravitational time dilation. This relativistic effect, highlighted in the…
Measurement of Gravitational Time Dilation: An Undergraduate Research Project
M. Shane Burns, Michael D. Leveille, Armand R. Dominguez +10
General relativity predicts that clocks run more slowly near massive objects. The effect is small---a clock at sea level lags behind one 1000 m above sea level by only 9.4 ns/day.…
Precision lifetime measurement of the cesium level using ultrafast pump-probe laser pulses
Brian M. Patterson, Jerry F. Sell, Thomas Ehrenreich +4
Using the inherent timing stability of pulses from a mode-locked laser, we have precisely measured the cesium excited state lifetime. An initial pump pulse excites cesiu…
Collimated Blue and Infrared Beams Generated by Two-Photon Excitation in Rb Vapor
J. F. Sell, M. A. Gearba, B. D. DePaola +1
Utilizing two-photon excitation in hot Rb vapor we demonstrate the generation of collimated optical fields at 420 nm and 1324 nm. Input laser beams at 780 nm and 776 nm enter a hea…
Polarization and relaxation of radon
E. R. Tardiff, J. A. Behr, T. E. Chupp +9
Investigations of the polarization and relaxation of Rn by spin exchange with laser optically pumped rubidium are reported. On the order of one million atoms per shot were…
