A method for selective resonance ionization of odd isotopes using the Rydberg level is developed for the analysis of calcium-41 in concrete waste. In this study, we observed the energy shifts of the ns and nd levels of calcium-43 Rydberg atoms due to the hyperfine structure of the ion ground state.
