Abstract

The smectic-A phase of a liquid crystal is characterized by a one-dimensional mass density wave in a three-dimensional liquid. High-resolution x ray measurements in the smectic-A phase of octyloxycyanobenzylidene (8OCB) show that the order-parameter scattering does not exhibit normal Bragg line profiles but rather corresponds to a power-law singularity of the form (q∥-q0)-2, with q∥ being the longitudinal wave-vector component. Also, the transverse line profile is anomalous. © 1977 The American Physical Society
