title: Static multipole polarisabilities and second-order Stark shift in francium.
abstract: 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.  This approach is also shown to yield reasonable results for other alkali atoms.  Second-order Stark shift for the ground state of francium is presented as a function of field strength for possible future experimental comparison.
