Sympathetic cooling of trapped Th3+ alpha-recoil ions for laser spectroscopy

G. Zitzer, J. Tiedau, M. V. Okhapkin +5

Sympathetic cooling of Th${}^{3+}$ ions is demonstrated in an experiment where ${}^{229}$Th and ${}^{230}$Th are extracted from uranium recoil ion sources and are confined in a linear Pa…
