I came across this question where there is a FCC lattice. It states that the lattice is a convolution of the simple cubic (whose reciprocal lattice is itself) with a basis (that consists of 2 points).(adsbygoogle = window.adsbygoogle || []).push({});

When finding the reciprocal of this BCC lattice,

FourierTransform(BCC)

= FourierTransform(SimpleCubic * Basis)

= FourierTransform(SimpleCubic) . FourierTransform(Basis)

Now what is the fourier transform of the basis which consists of 2 points? Thanks for any help to clear up this confusion!
