The scattering geometry of the z-axis mode. The incident X-ray wavevector is ki, the diffracted wavevector is kf and the scattering vector is Q. The incoming and outgoing angles are βin and βout, respectively. The scattering angle is 2θ and its projection onto the sample surface is Φ. The angular deviation of the diffracted beam with the ω rotation of the sample is denoted by X and Y. |
