Query: Non-relativistic scattering of a spin-1/2 particle off a self-dual
  monopole   The non-relativistic scattering of a spin-1/2 particle off a self-dual
monopole reduces, for large distances, to the dyon problem, studied previously
by D'Hoker and Vinet. The S matrix (calculated by Zwanziger's algebraic method
based on the o(3,1)\oplus o(3) dynamical symmetry, discovered by D'Hoker and
Vinet) is shown to factorize into the product of the spinless S-matrix, S_0,
with a spin-dependent factor. The total cross-section is identical to the one
found in the spinless case.
