Abstract

Laser spectroscopy is a technique that can be used to probe the electronic structure of atoms/ions. The Collinear Fast Beam Spectroscopy (CFBS) group at TRIUMF uses this technique to probe the hyperfine structure of rare isotopes produced on-site. The hyperfine structure of an atom, which arises from the various interactions between the atom's/ion's electrons and nucleus, can be used to infer properties, such as the spin and mean squared charge radius, of the atom's nucleus. However, the geometry of the experimental set up at TRIUMF allows for the possibility of optical pumping, a process by which the atoms/ions being probed have their electronic ground state distribution changed before the hyperfine structure can be measured. This in turn ...
