title: Circular polarization of vacuum ultraviolet light by piezobirefringence.
abstract: An instrument has been constructed that can produce any degree of elliptical polarization from linear to circular in the vacuum uv range 1050 A to 1450 A using a piezobirefringent retarder of LiF. The apparatus is conveniently described by the Mueller matrices. One of the piezobirefringence constants, P(11) - P(12), ranged from 4.0-10.0 x 10(-13) cm(2)/dyn for various samples of LiF, and the index of refraction at 1216 A was 1.79 +/- 0.14.
