I'm answering a question where it becomes necessary to know the closest face of the BZ in a bcc structure. The answer is given as +/- (2*pi) / (sqrt(2)*a) where a is the cubic lattice parameter.(adsbygoogle = window.adsbygoogle || []).push({});

I would have thought the Answer would have been sqrt(3)*a / 4. Where does the pi come from?

Cheers in advance.
