Magneto-optic trapping of {sup 210}Fr
- Department of Physics, State University of New York, Stony Brook, New York 11794-3800 (United States)
The alkali element francium has no stable isotopes and has eluded extensive study because sufficient quantities have not been available for detailed investigations. More than 1000 {sup 210}Fr atoms have now been contained in a magneto-optic trap. This number is sufficient to allow extensive studies of Fr atomic properties that are necessary input for future tests of fundamental interactions. The {sup 210}Fr ({ital T}{sub 1/2}=3.2 min) were created in the nuclear reaction {sup 197}Au({sup 18}O,5{ital n}){sup 210}Fr and were extracted from the target and injected into the trap. The ratio of the trap loading rate to the production rate in the target was 10{sup {minus}4}, which is 50 times larger than in previous experiments with {sup 79}Rb. {copyright} {ital 1996 The American Physical Society.}
