    "abstract": "Relativistic formulas for the electric quadrupole moment of a hydrogenlike\natom, induced by the hyperfine interaction, are derived for $ns_{1/2}$ and\n$np_{1/2}$ states. Both the magnetic dipole and electric quadrupole hyperfine\ninteractions are taken into account. The formulas are valid for ions with\narbitrary nuclear charge and spin. The induced quadrupole moment is compared\nwith the nuclear quadrupole moment for a wide range of hydrogenlike ions.",
