摘要：

We report the successful trapping of 6 x 10(6) Rb-82 (t(1/2) = 75 S) atoms with a trap lifetime of similar to 30 s in a magneto-optical trap that is coupled to an off-line mass separator. Efficient sample introduction is achieved by implanting Rb-82 ions into a small yttrium catcher foil located inside the trapping cell. Upon heating, the radioactive atoms are released from the foil and trapped without significant gas loading. This advancement makes a variety of high-precision electroweak interaction experiments possible, including the measurement of beta-decay correlations associated with spin-polarized Rb-82 nuclei.
