S. Mannervik et al., LASER PROBING OF IONS IN A STORAGE-RING - A METHOD FOR SELECTIVE DETERMINATION OF LIFETIMES OF METASTABLE STATES, Hyperfine interactions, 108(1-3), 1997, pp. 291-304
A collinear laser probing technique is introduced for use in ion stora
ge rings. This method can be used for high resolution studies of the d
ecay properties of metastable states in ions. An experiment on singly
charged xenon utilizing this technique is presented. By selective exci
tation of individual hyperfine states a drastic hyperfine induced quen
ching was observed. Systematic effects from ion beam neutralization in
the rest gas and mixing effects occurring in the bending magnets are
discussed.
