Query: Stationary scattering theory for repulsive Hamiltonians   In the present paper we discuss stationary scattering theory for repulsive
Hamiltonians. We show the existence and completeness of stationary wave
operators and unitarity of the scattering matrix. Moreover we completely
characterize asymptotic behaviors of generalized eigenfunctions with minimal
growth in terms of the scattering matrix. In our argument the radiation
condition bounds for limiting resolvents play major roles. In fact, it is used
to construct the stationary wave operators.
