## Main Question or Discussion Point

Hi,

I would like to confirm my intuition about a bessel integral from you guys.

The integral is: Integrate[ (1/r) * J[2,2*pi*phi*r] ] from 0 → ∞ with respect to r.

J[2,2*pi*phi*r] is a second order bessel. Integrals with 1/x from 0 to Inf are divergent. Sure enough, this one is gonna diverge so mathematica says. But is there anything I might be able to do to stop this integral from diverging?

Thanks in advance for any insight!
