Abstract: | Using small-angle X-ray scattering, the repeat distance vs. temperature is measured for a homologous series of multilamellar vesicles of lecithins with varying acyl chain length in
excess water condition around the lipid main transition. A systematic chain length dependence is found which is in accordance
with a bending rigidity renormalization and critical unbinding of the lamellae close to the transition, as previously suggested
in H?nger et al. Phys. Rev. Lett. 72, 3911 (1994)].
