Query: Descriptions of Carbon isotopes within relativistic
  Hartree-Fock-Bogoliubov theory   Within the relativistic Hartree-Fock-Bogoliubov (RHFB) theory, the structure
properties of Carbon isotopes are systematically studied. In order to reproduce
the experiment data, we take the finite-range Gogny D1S with a strength factor
$f$ as the pairing force. The self-consistent RHFB calculations with
density-dependent meson-nucleon couplings indicate the single-neutron halo
structures in both $^{17}$C and $^{19}$C, whereas the two-neutron halo in
$^{22}$C is not well supported. It is also found that close to the neutron drip
line there exists distinct odd-even staggering on neutron radii, which is
tightly related with the blocking effects and correspondingly the blocking
effect plays a significant role in halo formation.
