Four fundamental.methods are described for recording the intensity of radially symmetric scattered radiation as a function of scattering angle.
The first and second arrangements utilize the conventional incident pencil of radiation. The first scheme scans a diameter of the scattering pattern in the customary fashion. The second scheme scans with axial translation of a circular ring aperture.
The third scheme uses a divergent incident beam on a ring specimen and scans axially with a pinhole detector. The fourth scheme employs a beam from a ring source converging onto the specimen and records the intensity on the axis as a function of the angle of convergence, as the specimen is translated axially.
The third arrangement is illustrated with an example which demonstrates its feasibility.
