Miyabe, Masabumi   ; Oba, Masaki ; Kato, Masaaki; Wakaida, Ikuo  ; Watanabe, Kazuo

High precision resonance ionization spectroscopy has been applied to determination of an accurate ionization potential of $$^{40}$$Ca. Three-step resonant excitation with single-mode extended cavity diode lasers populates a series of ${it 4snp}$ ($$^{1}$$P$$_{1}$$) and ${it 4snf}$ ($$^{1}$$F$$_{3}$$) Rydberg states in the rage of ${it n}$=20-150. By using an extended Ritz formula for quantum defect, the series convergence limit has been determined to be 49305.9240 (20) cm$$^{-1}$$ with the accuracy improved one order of magnitude higher than previously reported ones.
