The radioactive element francium is of great interest in many laboratories because, as an alkali, it is the heaviest atom in which the atomic properties can presently be calculated to better than 1%. The electron-nucleus interactions in heavy atoms a

We have trapped over 250 000 210Fr in a new on-line high efficiency magneto-optical trap (MOT). We describe the new apparatus and present an overview of high-efficiency MOTs for trapping rare isotopes. These traps depend on three critical components:

We describe several methods for efficiently injecting a small number of radioactive atoms into a laser trap. The characteristics of laser traps that make them desirable for physics experiments are discussed and several different experimental directio

The alkali element francium has a simple electronic structure, and copious amounts of a wide range of isotopes can be produced in present and future rare isotope facilities. The atomic parity violating weak interaction in Fr is 18 times larger than i

The francium atom offers an excellent laboratory to study electron-nucleus interactions. As the heaviest alkali, its atomic properties can be calculated with high precision, and laser trapping methods now allow precision optical spectroscopy of many

The difficult problem of quickly slowing and cooling nuclear reaction products so that they can be injected into a laser trap has been solved by several groups and there are now strong efforts to work with the trapped atoms. The atoms are confined in

We have tested and developed an ion beam apparatus for transporting alkali atoms made in heavy-ion reactions. Stopped recoils diffuse out of a hot thick target, are surface ionized, and extracted into a low-energy ion beam with efficiencies of approx

The hyperfine interaction couples the atomic electrons and the nucleus, and because of this interaction, there is a fundamental link between the fields of atomic physics and nuclear physics. Of course, information flows in both directions through thi

Laser spectroscopic observations of nuclear reaction products produced with intensities of less than 104 atoms/second are now possible with several different methods. We describe the recoil into gas method which has recently been successful. This met
