dc.description.abstractThe Francium Group at TRIUMF is preparing to study the parity-violating electric dipole amplitude for the 7s → 8s transition in francium. The parity-violating weak force contributes very small perturbations of electron wave functions which can be explored with spectroscopy for this transition in heavy alkali atoms. This thesis reports on isotope-shift measurements for 7s 1/2 → 8s 1/2 and transitions in isotopes 208−211 Fr and 213 Fr which will help us interpret future atomic parity non-conservation investigations for this element. An ultra low expansion cavity has been implemented in a new laser locking system to support such measurements. With this cavity, we have begun preliminary single-photon Stark-shift investigations of the analogous 5s → 6s transition in 87 Rb. This thesis also reports on other developments at the francium trapping facility such as new transparent indium tin oxide electric field plates for Stark-shift investigations and implementing new OTS dryfilm coatings in our capture cell.en_US
