Precision long-term measurements of beta-decay-rate ratios in a controlled environment
S. D. Bergeson, J. B. Peatross, M. Ware
We report on measurements of relative beta-decay rates of Na-22, Cl-36, Co-60, Sr-90, Cs-137 monitored for more than one year. The radioactive samples are mounted in an automated s…
Measurement and simulation of laser-induced fluorescence from non-equilibrium ultracold neutral plasmas
A. Denning, S. D. Bergeson, F. Robicheaux
We report new measurements and simulations of laser-induced fluorescence in ultracold neutral plasmas. We focus on the earliest times, when the plasma equilibrium is evolving and b…
Plasma Oscillations and Expansion of an Ultracold Neutral Plasma
S. Kulin, T. C. Killian, S. D. Bergeson +1
We report the observation of plasma oscillations in an ultracold neutral plasma. With this collective mode we probe the electron density distribution and study the expansion of the…
Creation of an Ultracold Neutral Plasma
T. C. Killian, S. Kulin, S. D. Bergeson +3
We report the creation of an ultracold neutral plasma by photoionization of laser-cooled xenon atoms. The charge carrier density is as high as 2 x 10^9 cm^-3, and the temperatures…
