So I know that the basis vectors of an FCC in a symmetric form are:(adsbygoogle = window.adsbygoogle || []).push({});

[tex] a = \frac{a}{2}(\hat{x} + \hat{y}) [/tex]

[tex] b = \frac{a}{2}(\hat{y} + \hat{z}) [/tex]

[tex] c = \frac{a}{2}(\hat{x} + \hat{z}) [/tex]

And that the reciprocal lattice vectors are the basis vectors of the BCC cells.

I'm having a hard time doing the cross products correctly, so if anyone could walk me through an example of the math that would be very helpful.
