Figure 3
The Ewald sphere showing lines of constant ψ, `longitude', around the sphere where the polar axis is along k0 and lines of constant scattering angle 2θ, `latitude', along with a ψ–2θ projection for a cubic diamond crystallite rotated around its [111] axis, with the incident beam normal to this axis. Zero ψ lies in the plane normal to the [111] axis. |
