Bravais lattice determination from a single CBED pattern

Summarized in this paper is a new method of Bravais lattice determination using an arbitrary single convergent beam diffraction (CBED) pattern. The method uses the deficiency lines of high order and high order lane zone (HOLZ) reflections to measure the primitive cell of the zone axis, and use the standard Kirvy and Gruber procedure to reduce this arbitrary primitive cell to a unique Niggli cell, and thus the Bravais cell. The method requires only a single CBED pattern taken slightly off zone axis center in the so-called kinematic orientation and assumes that both camera length and high voltage are known with reasonable accuracy.
