Abstract
High-resolution spectroscopy is reported in the paper. Transitions with a frequency comb laser is calibrated. First results on the resonance lines of atomic carbon (at 94.5 nm) and of atomic magnesium (at 202 nm) is also presented. Results include accurate determination of transition isotope shifts.
