摘要：
Scattering from a discrete quasi-Hermitian delta function potential is studied and the metric operator is found. A generalized continuity relation in the physical Hilbert space H-phys is derived and the probability current density is defined. The reflection R and transmission T coefficients computed with this current are shown to obey the unitarity relation R + T = 1.
