Within the frame of the random phase approximation, the equation of motion for normal modes in an electron gas is solved by the iteration method and dispersion relations of a plasmon for the paramagnetic and ferromagnetic electron gases are obtained. The dispersion relation in the paramagnetic state agrees with that given by Kanazawa et al.. It is shown that there is no difference between the constant terms in the dispersion relation with respect to the momentum of aplasmon in the paramagnetic and ferromagnetic states, but coefficients of the terms proportional to the square of the momentum in the dispersion relation are different in the paramagnetic and ferromagnetic states. This difference is roughly estimated for the real ferromagnetic metals, iron, cobalt and nickel, and a possibility of the observation of this difference is discussed.
