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 show a remarkable agreement with calculated ab initio properties to a degree that is comparable with… 

Fundamental symmetries studies with cold trapped francium atoms at ISAC

Francium combines a heavy nucleus (Z = 87) with the simple atomic structure of alkalis and is a very promising candidate for precision tests of fundamental symmetries such as atomic parity

Francium sources and traps for fundamental interaction studies

Abstract.Francium is one of the best candidates for atomic parity nonconservation (APNC) and for the search of permanent electric dipole moments (EDMs). APNC measurements test the weak force

The FrPNC Experiment, weak interaction studies in Francium at TRIUMF

Francium is an excellent system to study the nuclear weak force due to its large nucleus and relatively simple atomic structure. The FrPNC experiment has a facility to produce cold trapped atomic

Measuring the Fr weak nuclear charge by observing a linear stark shift with small atomic samples.

TLDR
The chirality of ground-state alkali atoms in E and B fields is studied, dressed with a circularly-polarized beam near-detuned from an E-field-assisted forbidden transition such as 7S-8S in Fr.
