A general formalism is worked out for the description of one-dimensional scattering by separable non-local potentials and constraints on transmission and reflection coefficients are derived in the cases of P, T, or PT invariance of the Hamiltonian. The one-dimensional Yamaguchi potential is discussed in detail. © Institute of Physics, Academy of Sciences of Czech Republic 2006.
