Query: Appraising nuclear octupole moment contributions to the hyperfine
  structures in $^{211}$Fr   Hyperfine structures of $^{211}$Fr due to the interactions of magnetic dipole
($\mu$), electric quadrupole ($Q$) and magnetic octupole ($\Omega$) moments
with the electrons are investigated using the relativistic coupled-cluster
(RCC) theory with an approximation of singles, doubles and important valence
triples excitations in the perturbative approach. Validity of our calculations
are substantiated by comparing the results with their available experimental
values. Its $Q$ value has also been elevated by combining the measured
hyperfine structure constant of the $7p \ ^2P_{3/2}$ state with our improved
calculation. Considering the preliminary value of $\Omega$ from the nuclear
shell-model, its contributions to the hyperfine structures up to the $7d \
^2D_{5/2}$ low-lying states in $^{211}$Fr are estimated. Energy splittings of
the hyperfine transitions in many states have been assessed to find out
suitability to carry out their precise measurements so that $\Omega$ of
$^{211}$Fr can be inferred from them unambiguously.
