This page performs various computations on lattices using NIST*LATTICE, "A Program to Analyze Lattice Relationships" (Version of Spring, 1991) by Vicky Lynn Karen and Alan D. Mighell, National Institute of Standards and Technology, Materials Science and Engineering Laboratory, Gaithersburg, Maryland 20899. [V. L. Karen and A. D. Mighell, NIST Technical Note 1290 (1991); V. L. Karen & A. D. Mighell, U.S. Patent 5,235,523].
|R||Rhombohedral cell on hexagonal axes (optional for
rhombohedral settings). |
Note: use "P" for hexagonal cells with hexagonal and trigonal spacegroups.
