Abstract

Neutron diffraction data have been obtained from a rippled phase of multibilayer stacks containing mixtures of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) and 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE). In orientated bilayers neutron diffraction patterns show Bragg peaks near to the meridian and displaced from the usual long spacings. These off-axis reflections are assigned to a rippled phase and it is suggested it is formed as a transition phase between L α and H II phases.
