Abstract

A new technique based on the combination of laser photodetachment and resonance ionization spectroscopy has been used to characterize the state composition of a fast, negative-ion beam of barium and to determine the binding energies of its long-lived components, the metastable 5d6s6p⁴F_9/2 state and the 6s²6p²P_3/2,1/2 ground state, with an accuracy previously inaccessible for the weakly bound, negative alkaline-earth ions. Additional information about the Ba^\ensuremath- states was obtained from lifetime studies in the ASTRID storage ring.
