Possibilities for francium spectroscopy in a light trap
نویسندگان
چکیده
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 excited states. These measurements would then open the path to investigations of parity-violating transitions in francium.

Spectroscopy with trapped francium: advances and perspectives for weak interaction studies
Francium is a candidate for atomic parity non-conservation (PNC) experiments. Its simple atomic structure has been the subject of extensive experimental research facilitated by the ability to trap and cool significant numbers of atoms. The studies include the location of energy levels, their hyperfine splittings and their lifetime. All of these levels are close to the ground state. The results ...

متن کاملEfficient inter-trap transfer of cold francium atoms
We report on the status of the FrPNC experiments and summarize our plans for measurements of parity non-conservation (PNC) in a sample of cold francium. The FrPNC collaboration has commissioned a laser cooling apparatus at the TRIUMF accelerator that collects and cools francium atoms for PNC experiments. We have recently demonstrated the robust, high efficiency transfer (50 %) of laser cooled f...
متن کاملIsotope Shifts in Francium Isotopes
We present the isotope shifts of the 7s1/2 to 7p1/2 transition for francium isotopes 206−213Fr with reference to 221Fr collected from two experimental periods. The shifts are measured on a sample of atoms prepared within a magneto-optical trap by a fast sweep of radio-frequency sidebands applied to a carrier laser. King plot analysis, which includes literature values for 7s1/2 to 7p3/2 isotope ...

The electron-nucleus interactions in heavy atoms are stronger than in lighter alkalis, and are more sensitive to weak interaction effects in nuclei, such as anapole moments, electric dipole moments and other parity violating effects. The abi...
