%X The energy levels of bound states for one dimensional Dirac equation are doubly degenerate provided that the scalar like potential is greater than the vector like potential. Arbitrary two wave functions with different eigenenergies and two wave functions with the same eigenenergy are orthogonal to each other. For a pure scalar potential the zero energy bound state does exist, and the fractional charge does exist.
