GOMEZ RODRIGUEZ, A.  and  ROMEU CASAJUANA, D.. Reciprocity relations for Bollmann's o-lattice. Rev. mex. fis. [online]. 2007, vol.53, n.2, pp.139-143. ISSN 0035-001X.

A reciprocity relation for Bollmann's O-lattice is introduced. This result completes the existing Grimmer's reciprocity results between coincidence sites and displacement shift complete lattices. We show that the lattice generated by a*_i - b*_i (i = 1, 2, 3) is reciprocal to the O-lattice. This result, supported by Multislice calculations, indicates that it is possible to observe the O-lattice under an electron microscope using annular apertures, thus allowing the study of strain fields existing in interfaces or between a thin film growing onto a crystalline substrate.
