- 7S(1/2) ? 9S(1/2) two-photon spectroscopy of trapped francium.
- We report on the spectroscopic measurement of the (210)Fr 9S(1/2) energy obtained by two-photon excitation of atoms confined and cooled in a magneto-optic trap. The resonant intermediate level 7P(3/2)...

- Lifetime measurement of the 9s level of atomic francium.
- We use two-photon resonant excitation and time-correlated single-photon counting techniques on a sample of 210Fr atoms confined and cooled in a magneto-optical trap to measure the lifetime of the 9s e...

- Static multipole polarisabilities and second-order Stark shift in fran...
- The multipole polarisability of the ground state of francium is calculated by utilising both the variational technique of Davison and the quantum defect theory underlying the Bates-Damgaard method. Th...
