Topics in high resolution spectroscopy of stored ions

Recent developments in stored ion spectroscopy are discussed with emphasis on the following aspects: (1) very high resolution experiments; (2) precision spectroscopy of one-electron ions; (3) measurement of the magnetic moment of the bound electron; and (4) feasibility of external ion injection to extend ion storage techniques to highly charged and possibly radioactive ions. The question of what can be learned from these experiments about nuclear structure and quantum electrodynamical contribution to the hyperfine interaction and the atomic Zeeman effect is addressed.
