Jan 2018 Significant Progress in Helium Spectroscopy
We develop laser-based ultrasensitive trace analysis methods. By performing precision measurements on atoms, molecules, and nuclei, we study fundamental problems in physics and chemistry, and develop applications in the earth and environmental sciences.
Radioactive isotope tracers are natural clocks in the environment.
The neutral helium atom, with only two electrons, can be theoretically understood to a high degree of precision.
Detection of Atmospheric Species by Laser Spectroscopy.
The Bolztmann constant kB is one of the fundamental constant in physics.
Molecular hydrogen is subject to most physical phenomena relevant to the chemical binding in more complicated molecules. .
225 Ra EDM
An intrinsic electric dipole moment (EDM) of an atom signifies the violation of both parity (P) and time-reversal (T) symmetries.
