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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
