I'm trying to calculate the 3D fourier transform of this function:

$$\frac{1}{(x^2+y^2+z^2)^{1/2}}$$

Any help would be appreciated, thanks.

    @DJC Not an exact duplicate, as the question you linked to has $3/2$ in the denominator rather than $1/2$, but similar solution methods will probably work2011-10-10

    Hi, if a similar method would work, how would you implement it? The method used before was 2D (it relied on using cylindrical bessel functions) and I was unable to adapt it to this question.2011-10-10

    The downvoter should perhaps explain the reason for the downvote.2011-10-10

    Have you tried spherical coordinates?2011-10-10
