Invited Speaker / Conférencier invité

Our research group has investigated the spectra of several gases of environmental importance using our 3-channel laser spectrometer or the experimental facility at the far-infrared beamline at the Canadian Light Source. Our results have been used by others through our contributions to the HITRAN and GEISA databases used by the atmospheric community and we have made our own contributions to the...

548. CLS Synchrotron FIR Spectroscopy of High Torsional Levels of CD3OH: The Tau of Methanol

Oral (Non-Student) / orale (non-étudiant)

Structure from high torsional levels of the CD${}_3$OH isotopologue of methanol has been analyzed in Fourier transform spectra recorded at the Far-Infrared beamline of the Canadian Light Source synchrotron in Saskatoon. Energy term values for $A$ and $E$ torsional species of the third excited torsional state, v${}_t$ = 3, are now almost complete up to rotational levels $K$ = 15, and thirteen...

Quantum defects are useful in interpreting high energy atomic states in terms of simple Hydrogenic energy levels. We will find the energy levels for 1snp singlet and triplet P state Helium from $n=2$ to $n=12$ with some of the most accurate helium atom calculations to date using the exact non-relativistic Hamiltonian with wave functions expanded in a basis set of Hylleraas...

446. Precision Measurement of Lithium Hyperfine and Fine Structure Intervals

Oral (Non-Student) / orale (non-étudiant)

A number of experiments have precisely measured fine and hyperfine structure splittings as well as isotope shifts for several transitions at optical frequencies for 6,7Li [1]. These data offer an important test of theoretical techniques developed by two groups to accurately calculate effects due to QED and the finite nuclear size in 2 and 3 electron atoms. The work by multiple groups...

675. Dual Co-Magnetometer using Xe129 for Measurement of the
 Neutron’s Electron Dipole Moment

A new high-density ultra cold neutron source is being constructed and developed at TRIUMF in Vancouver, BC with collaborators from Japan and several Canada research groups. One of the first goals of this collaboration is to measure the electric dipole moment (EDM) of the neutron to an uncertainty of <10${}^{-27}$ e-cm. To measure the nEDM, a magnetic resonance (MR) experiment on polarized...
