摘要：
Rare calcium isotope ions, 42Ca+ and 44Ca+, were efficiently separated from a laser-cooled ionic cloud in a linear Paul trap which was loaded from an atomic source of a natural isotope mixture of calcium, in spite of their negligibly small abundances (0.647% and 2.086%, respectively) compared with that of 40Ca (96.94%). Selective heating and cooling that arise from the isotope shifts were mainly used for the elimination of the isotopes; selective heating and cooling enable flexible separation when combined with other mechanisms such as the inherent mass selectivity of RF traps.
