      abstract     = {Polyelectrolytes in dilute solutions (0.01 mmol/L) adsorb
                      in a two-dimensional lamellar phase to oppositely charged
                      lipid monolayers at the air/water interface. The interchain
                      separation is monitored by Grazing Incidence X-ray
                      Diffraction. On monolayer compression, the interchain
                      separation decreases to a factor of two. To investigate the
                      influence of the electrostatic interaction, either the line
                      charge density of the polymer is reduced (a statistic
                      copolymer with $90\%$ and $50\%$ charged monomers) or
                      mixtures between charged and uncharged lipids are used
                      (dipalmitoylphosphatidylcholine (DPPC)/
                      dioctadecyldimethylammonium bromide (DODAB)) On decrease of
                      the surface charge density, the interchain separation
                      increases, while on decrease of the linear charge density,
                      the interchain separation decreases. The ratio between
                      charged monomers and charged lipid molecules is fairly
                      constant; it decreases up to $30\%$ when the lipids are in
                      the fluid phase. With decreasing surface charge or linear
                      charge density, the correlation length of the lamellar order
                      decreases.},
