Abstract

Abstract : We investigated a promising three-step resonance ionization scheme of strontium (Sr) 5s 2 1 S0 ⟶ 5s5p 3 P 1 ° ⟶ 5s5d 3 D2 ⟶ 4dnp (or 4dnf, n = 39) using the first-step intercombination transition for the enhancement of isotope selectivity. The power broadening observed in the 2 nd transition indicates that laser power of less than 0.2 mW is sufficient for saturating this transition. Isotope separation can be successfully expected with application of the 3 rd transition due to the narrow width of the 4dnp (or 4dnf, n = 39) autoionization level, paving the way for analysis of trace 90 Sr in environmental applications.
