Title: Coherent soft-X-ray dynamic light scattering from smectic-A films
Abstract: We have used coherent soft-x-ray dynamic light scattering at the Bragg to measure the thermally driven layer fluctuations in freely films of five different smectic-A liquid crystals: 40.8, 70.7, 80CB, and 100CB. The measured relaxation times at a scattering wave corresponding to the interlayer spacing (2 pi q(-1) approximate 30 Angstrom) ranged from 2 to 60 mu s for films from 4 to 50 mu m Thus, we have achieved the same time resolution as conventional dynamic light scattering, but with 100 times higher spatial resolution.
