Plz, help to integrate this:

[tex] /int_{-/infinity}^{+/infinity}dk /frac{exp(ikx)}{k^2+a^2}[ /tex ]

[tex] /int_{-/infinity}^{+/infinity}dk /frac{exp(ikx)}{k^2+a^2}[ /tex ]

What I think is that it is a divergent integral. But it is given in the book. So, maybe it has any physical meaning ?!

I just answered a similar question yesterday. Here's the answer: "Set up a contour integral and use the residue theorem." It's not divergent.
