چکیده

Light forces acting on radioactive atoms confine them in very dense and cold samples achieving large phase space density. We describe the processes of radioactive atom production, reduction of their velocity and capture. The trapped atoms form excellent sources for the study of atomic parity non-conservation, β decay asymmetry, other weak force processes, and α decay asymmetry.

Experimental study of vapor - cell magneto - optical traps for efficient trapping of radioactive atoms

We have studied magneto-optical traps (MOTs) for efficient on-line trapping of radioactive atoms. After discussing a model of the trapping process in a vapor cell and its efficiency, we present the results of detailed experimental studies on Rb MOTs. Three spherical cells of different sizes were used. These cells can be easily replaced, while keeping the rest of the apparatus unchanged: atomic ...

Commissioning of the Francium Trapping Facility at TRIUMF

We report on the successful commissioning of the Francium Trapping Facility at TRIUMF. Large laser-cooled samples of francium are produced from a francium ion beam delivered by the ISAC radioactive ion beam facility. The ion beam is neutralized on an yttrium foil, which is subsequently heated to transfer the atoms into the magneto-optical trapping region. We have successfully trapped 207Fr, 209...

Theory of magic optical traps for Zeeman-insensitive clock transitions in alkali-metal atoms

Precision measurements and quantum-information processing with cold atoms may benefit from trapping atoms with specially engineered, “magic” optical fields. At the magic trapping conditions, the relevant atomic properties remain immune to strong perturbations by the trapping fields. Here we develop a theoretical analysis of magic trapping for especially valuable Zeeman-insensitive clock transit...

Hyperfine Interactions 74(1992)23-29 23 LASER SPECTROSCOPY OF NUCLEAR REACTION PRODUCTS: RECENT RESULTS AND FUTURE PROSPECTS

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 method is not Dopplerfree, but can give reasonable spectra if the resolution requirements of the spectra are not too high. It has the great advantage ...

Possibilities for francium spectroscopy in a light trap

An experimental program is under way to capture neutral francium atoms in a magneto-optic trap. Production and transport of the radioactive Fr atoms near to the trapping region have been tested, with a steady state of 107 atoms. If one hundred atoms are captured from the Maxwel l -Bol tzmann distribution into a magneto-optic trap, this will be a sufficient number for spectroscopy of the unknown...
