Phys. Rev. Lett. 76, 3522–3525 (1996)Magneto-Optic Trapping of 210FrReceived 13 December 1995; published in the issue dated 6 May 1996 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 210Fr 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. © 1996 The American Physical Society URL:
