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

Isotope-selective resonance ionization of strontium via an autoionization level is effective for the analysis of strontium-90 in marine samples. In this study, we observed the Stark shift of some autoionization levels under an electric field of the order of 1 V/cm or less, from which the polarizabilities of these levels were estimated.
