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…
Low phase noise diode laser oscillator for 1S-2S spectroscopy in atomic hydrogen
N. Kolachevsky, J. Alnis, C. G. Parthey +3
We report on a low-noise diode laser oscillator at 972 nm actively stabilized to an ultra-stable vibrationally- and thermally compensated reference cavity. To increase the fraction…
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 oxygen with a series of pulsed electromagnetic coils: A molecular coilgun
Edvardas Narevicius, Adam Libson, Christian G. Parthey +4
We report the stopping of a molecular oxygen beam, using a series of pulsed electromagnetic coils. A series of coils is fired in a timed sequence to bring the molecules to near-res…
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…
Towards magnetic slowing of atoms and molecules
E. Narevicius, C. G. Parthey, A. Libson +3
We outline a method to slow paramagnetic atoms or molecules using pulsed magnetic fields. We also discuss the possibility of producing trapped particles by adiabatic deceleration o…
