description

As pointed out by Dehmelt in 1973, optical transitions between ground- and metastable states of ions offer intrinsically very narrow natural lines and consequently may be used as frequency references in the optical domain. Several ions are considered as possible candidates and the measurement of their metastable state lifetime is being discussed. In the submillimeter region fine structure transitions between metastable ionic states have natural line-Q’s of the order of 1012. We propose to use Ca+ as a possible candidate to induce and detect such a transition.
