Figure 1
A schematic diagram indicating the planes of the two cuts, one parallel and the other perpendicular to the plane of bedding of the sample rock. The unique axis is the normal to the bedding plane. For each orientation of the sample, the scattered neutron beam results in a pattern on the two-dimensional detector. The scattering has circular (azimuthally symmetric) contours when the beam is incident along the Z direction on the sample cut parallel to the bedding plane XY, and elliptical (azimuthally asymmetric) contours when the beam is incident along the X direction on the sample cut perpendicular to the bedding plane YZ. |
