摘要：

High-resolution x-ray and optical studies were peformed on oriented samples of the recently discovered smectic-A* phase. We confirm that this phase exhibits smectic-A layers as well as a macroscopic helical strcucture with the helical axis parallel to the layer planes. Furthermore, we demonstrate that the observed scattering can be explained by a cylindrical structure factor that is, within our instrumental resolution, a function in the radial direction and a Gaussian in the transverse direction as predicted by Renn and Lubensky for the twist grain boundary phase. © 1990 The American Physical Society.
