_diffrn_radiation_polarisn_ratio

Name

'_diffrn_radiation_polarisn_ratio'

Category: diffrn_radiation

Data type: numb

Enumeration range: 0.0 -> infinity

Definition

    	
   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).
