Laser Spectroscopy

The CFBS (Collinear Fast-Beam Laser Spectroscopy) experiment at TRIUMF is designed to exploit the high beam-intensity and radioisotope-production capability of TRIUMF's Isotope Separator and Accelerator (ISAC), as well as modern ion-trap beam-cooling and bunching techniques, in order to measure the hyperfine energy levels and isotope shifts of short-lived isotopes using laser spectroscopy. These measurements can be used to obtain nuclear structure information on exotic isotopes such as: nuclear magnetic moments (magnetic dipole and electric quadrupole), nuclear spin and changes in mean-square charge radii.
