Abstract

We performed isotope selective manipulation of laser cooled ions using the mass selectivity of an ion trap. We have investigated the possibility of realizing isotope selection for even Ca+isotopes, such as Ca40+ (abundance 96.9%), Ca42+ (0.647%), Ca44+ (2.09%), and Ca48+ (0.187%). We observed the behaviors of each isotope for the rf and dc voltages in the stable region of Mathieu equation. Even though the increase of the rf and dc voltages leads to rf heating of the trapped ions, the trapped ions were observed by the laser cooling technique. Furthermore, we demonstrated the selectivity and observation of a target isotope.
