The trapped ion apparatus has been assembled during the past year and successfully used to study the photodetachment of S- ions. A periodic dependence of the photodetachment cross section on the light frequency was observed for the first time in any atom. The oscillatory structure could be attributed to the excitation of the detached electrons to discrete cyclotron levels in the magnetic field. The experiments so far also indicate that state dependent photodetachment should provide an effective means for producing and detecting population differences in certain stored ionic species. Plans are now in preparation for studying the microwave spectrum of S- with this technique. Author
