Ann. Phys. 176, 159-180 (1987).

The scattering of nonrelativistic particles (either quantum mechanical or classical) by a magnetic field B is studied in any dimension \(\nu\geq 2\). \(B(x)\) is allowed to decay like \(| x|^{-3/2-\delta}\) \((\delta >0)\), as \(| x| \to \infty\). Assumptions are made about the field strengths and not about the potentials. A gauge is constructed for which the unmodified wave operators exist and are complete even though the corresponding classical motion need not be asymptotically free. The result also holds for Yang-Mills fields.
