    The "value" of the integral is infinity, a.k.a. it does not converge.
    Only for sin(kr)/r one can do the integration. Are you sure this is not what you meant? It looks like the typical integral coming from an integration over all space in spherical coordinates, which also introduces a Jacobian of r^2 sin(theta).
