Hello,
I tried the following integral:
Integrate[Exp[-I k3 x3]/(k12^2 + k3^2)^2,{k3,-Infinity,Infinity},
Assumptions -> k12!=0 && Im[k12] == 0 && Im[k3] == 0 && Im[x3] == 0]
The result in version 5 is
(Abs[k12]*MeijerG[{{1/2}, {}}, {{0, 1/2, 3/2}, {}},
(-(1/4))*k12^2*x3^2])/(k12^4*Sqrt[Pi])
But in version 4 is
(1 + Abs[k12] Abs[x3]) / Abs[k12]^2 * Exp[- Abs[k12] Abs[x3]]
How can I get last result from version 5?
Thanks in advance...
