Abstract

We have developed an apparatus integrating resonance-ionization, ion-trap, and laser-cooling techniques for an ultratrace radioactive isotope Sr90 analysis. Trapped Sr+90 isotope ions were laser cooled, and their 4dD3/22→5pP1/22 transition isotope shift was experimentally measured to be -281(17) MHz by comparing individual spectra of Sr+88 and Sr+90 ions. Crystallization of Sr+90 was carried out using the resonance frequency value confirmed in our experiment, and then Sr+90 individual ions were successfully observed.
