The influence of electron spin-interaction is investigated on the propagation of the symmetric and the anti-symmetric modes of the surface plasma waves in a quantum plasma slab. It is found that the electron spin-interaction effect enhances the phase and group velocities of the surface wave in a quantum plasma slab. It is also found that the phase and group velocities of the symmetric mode are always greater than those of the anti-symmetric mode in a quantum plasma slab. In addition, the influence of electron spin-interaction on the surface plasma wave diminishes the backward propagation domain of the anti-symmetric mode in bounded quantum plasmas. The variation of the physical characteristics of the surface quantum plasma waves due to the electron spin-interaction is also discussed.
