Improved Measurement of the Hydrogen 1S - 2S Transition Frequency
Christian G. Parthey, Arthur Matveev, Janis Alnis +14
We have measured the 1S - 2S transition frequency in atomic hydrogen via two photon spectroscopy on a 5.8 K atomic beam. We obtain Hz for t…
New Measurement of the 2S Hyperfine Interval in Atomic Hydrogen
N. Kolachevsky, A. Matveev, J. Alnis +3
An optical measurement of the 2S hyperfine interval in atomic hydrogen using two-photon spectroscopy of the 1S-2S transition gives a value of 177 556 834.3(6.7) Hz. The uncertainty…
Stopping Supersonic Beams with an Atomic Coilgun
Edvardas Narevicius, Adam Libson, Christian G. Parthey +4
We report the stopping of an atomic beam, using a series of pulsed electromagnetic coils. We use a supersonic beam of metastable neon created in a gas discharge as a monochromatic…
Coherent Slowing of a Supersonic Beam with an Atomic Paddle
E. Narevicius, A. Libson, M. F. Riedel +4
We report the slowing of a supersonic beam by elastic reflection from a receding atomic mirror. We use a pulsed supersonic nozzle to generate a 511 +/- 9 m/s beam of helium that we…
