T. Andersen et al., STRUCTURE AND DYNAMICS OF THE NEGATIVE ALKALINE-EARTH IONS, Journal of physics. B, Atomic molecular and optical physics, 30(15), 1997, pp. 3317-3332
Recent progress in experimental and computational methods for the stud
y of negative atomic ions has greatly improved the knowledge about the
structural and dynamic properties of the negative alkaline-earth ions
. This review deals in particular with the stable P-2 ground states in
Ca-, Sr-, and Ba- and with the metastable quarter states ((4)p, F-4,
and S-4) observed in Be-,Ca-, Sr-, and Ba-. Future perspectives are di
scussed.
