Item _diffrn_radiation.polarisn_ratio


Description 

              Polarisation ratio of the diffraction beam incident on the
               crystal. It is the ratio of the perpendicularly polarised to
               the parallel polarised component of the radiation. The
               perpendicular component forms an angle of
               '_diffrn_radiation.polarisn_norm' to the normal to the
               diffraction plane of the sample (i.e. the plane containing
               the incident and reflected beams).
