(a) Positions of the peaks A and A′ given by the out-of-plane scattering angle αf as a function of the incidence angle of the primary beam αi. (b) Calculated contribution of the scattering vector in the direction perpendicular to the surface (qz) for peaks A and A′ without (lines) and with corrections for both the inherent scattering path and optical refraction of X-rays (lines + symbols). For comparison, the qz value of the reciprocal lattice vector G110,z is given. |
