Rydberg excitation of a single trapped ion
T. Feldker, P. Bachor, M. Stappel +4
We demonstrate excitation of a single trapped cold Ca ion to Rydberg levels by laser radiation in the vacuum-ultraviolet at 122 nm wavelength. Observed resonances are id…

Mode shaping in mixed ion crystals of 40Ca2+ and 40Ca+
T. Feldker, L. Pelzer, M. Stappel +5
We present studies of mixed Coulomb crystals of 40Ca+ and 40Ca2+ ions in a linear Paul trap. Doubly charged ions are produced by photoionisation of trapped 40Ca+ with a vacuum ultr…
