    "abstract": "The Klein-Gordon equation with scalar potential is considered. In the\nFeshbach-Villars representation the annihilation operator for a linear\npotential is defined and its eigenstates are obtained. Although the energy\nlevels in this case are not equally-spaced, depending on the eigenvalues of the\nannihilation operator, the states are nearly coherent and squeezed. The\nrelativistic Poschl-Teller potential is introduced. It is shown that its energy\nlevels are equally-spaced. The coherence of time evolution of the eigenstates\nof the annihilation operator for this potential is evaluated.",
