  The recently derived sum rules for the scattering phase shifts of the
Overhauser geminals (being 2-body-wave functions which parametrize the pair
density together with an appropriately chosen occupancy) are generalized to
integral equations which allow in principle to calculate the momentum
distribution, supposed the phase sifts of the Overhauser geminals are known
from an effective parity-dependent interaction potential (screened Coulomb
repulsion).
