We are developing an isotope-selective analytical method for strontium-90 using laser resonance ionization via an autoionization level. In this study, the electric field in the ionization region was optimized to suppress the influence of the DC Stark effect on the obtained spectra. In addition, the coexisting elements affecting Sr atomic vapor formation are limited to sodium and potassium, so the sample pretreatment process is expected to be simplified.
