[3N02] Effect of external electric field on the resonance ionization of strontium via an autoionization level

Keywords:Strontium, Resonance ionization, Autoionization level, Stark shift

Isotope-selective resonance ionization of strontium via an autoionization level is developed for application to the analysis of strontium-90 in marine samples. In this study, we observed the Stark shift of the autoionization level caused by the external electric field for ion acceleration, whose effect on the resonance ionization was discussed.
