  We calculate the energy radiated during the scattering of two D-strings
stretched between two D3-branes, working from the Born-Infeld action for the
D-strings. The ends of the D-strings are magnetic monopoles from the point of
view of the gauge theory living on the D3-branes, and so the scattering we
describe is equivalent to monopole scattering. Our results suggest that no
energy is radiated during the scattering, in contrast to the monopole result of
ref. [2].
