title: Stretched polymers for X-ray linear and circular polarization.
abstract: X-ray linear dichroism at the iodine K-edge of Polaroid H-sheet is explored with a view to using stretched polymers for X-ray linear-polarization analysis. The potential use of such materials as phase plates for generating elliptically polarized beams is also considered.
