Chemiionization and spin exchange in collisions of triplet metastable atoms in a mixture of helium isotopes

Victor A. Kartoshkin

Cross sections of spin exchange and chemiionization in collisions of two triplet metastable helium atoms are calculated for different isotopes of helium. The data on the spin exchange cross sections for the systems studied are reported for the first time.

Laser cooling of a natural isotope mixture of Yb/sup +/ stored in an RF trap

K. Sugiyama, Jun Yoda

We demonstrate laser cooling of Yb/sup +/, produced by ionization of a natural isotope mixture, stored in an RF trap. One of the three major even isotopes was directly laser cooled and other isotopes were simultaneously trapped as a result of sympathetic cooling. It was possible to carry out laser cooling to the temperature at which the cloud-to-crystal phase transition occurs for /sup 174/Yb/sup +/, as observed in the case where enriched isotopes are used. We observed sudden drops of fluorescence owing to pumping to the /sup 2/F/sub 7/2/ state in the case of a small number of trapped Yb/sup +/ ions.>We demonstrate laser cooling of Yb/sup +/, produced by ionization of a natural isotope mixture, stored in an RF trap.
