Query: Some infinite divisibility properties of the reciprocal of planar
  Brownian motion exit time from a cone   With the help of the Gauss-Laplace transform for the exit time from a cone of
planar Brownian motion, we obtain some infinite divisibility properties for the
reciprocal of this exit time.
