Abstract. This paper is devoted to the scattering of photons at electrons in
models of non-relativistic quantum mechanical particles coupled
minimally to the soft modes of the quantized electromagnetic
field. We prove existence of scattering states involving an
arbitrary number of asymptotic photons of arbitrarily high energy.
Previously, upper bounds on the photon energies seemed necessary
in the case of $n>1$ asymptotic photons and non-confined,
non-relativistic charged particles.
