Calculation of the multipole moment Q₂₂

In version (v1.60r) of the code HFODD, a factor of $\sqrt{6}$ was missing in the values of the multipole moment Q₂₂ printed on the output file.

Values of the quadrupole moments Q₂₀ and Q₂₂ depend on the normalization factors which in the standard nuclear-physics applications are different than those used in electrodynamics, cf. Ref. [4]. In particular, the code HFODD (v1.75r) uses the normalization factors such that   where $\gamma$ is the standard angle measuring the non-axial quadrupole deformation [5].
