The symbol R is used especially _for_the ji^inbohedral^sy^tem. In Fig. 2-3, axes

of equal length in a particular system are given the same symbol to indicate their

equality, e.g., the cubic axes are all marked a, the two equal

or 2 log d = 2 log a - log \(h2 + fc2) + -—3] • (10-4) I (c/a)2J Suppose we now write

Eq. (10-4) for any two planes of a

by subscripts 1 and 2, and then subtract the two equations. We obtain 2 log d!
