How to find reciprocal lattice vectors

  1. Jul 23, 2015 #1
    So I know that the basis vectors of an FCC in a symmetric form are:
    [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.

    please read book by Kittle, introduction to solid state physics.
