_diffrn_radiation.polarisn_ratio
Name:_diffrn_radiation.polarisn_ratio
Alias:
_diffrn_radiation_polarisn_ratio
Definition:
Polarization ratio of the diffraction beam incident on the crystal.
It is the ratio of the perpendicularly polarized to the parallel
polarized 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).
Type: Real
