The result is well known, but i need more details about the integral below(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

\int \mathrm{d}^2x \frac{1}{|\mathbf{x}|} e^{- \mathrm{i} \mathbf{q} \cdot \mathbf{x}} = \frac{2 \pi}{q}[/tex]

I've done the Fourier transform of the Coulomb potential in 3D. But failed to get the right answer in 2D.

I did only a few practice about 2D integrals. Will anyone show me more details about it?

Thanks in advance!
