We have studied, for the first time,
the influence of the collective quantum effects in the nuclear wave
functions on the azimuthal anisotropy coefficients ε2,3
in the central Pb + Pb collisions at the LHC energies.
With the help of the energy weighted sum rule we demonstrate that the
classical treatment with the Woods-Saxon nuclear density
overestimates the mean square quadrupole moment
of the 208Pb nucleus by a factor of .
The Monte-Carlo Glauber simulation of the central Pb + Pb collisions
accounting for the restriction on the quadrupole moment
which allows to resolve the v2-to-v3 puzzle.
