Abstract: The author had considered the dispersion of LO phonon and had derive- a effective Hamiltonian of an exeiton in a polar crystal.In this paper,anal dytical formulas of the ground state energy and wave function of an exciton are derived respectively by means of variational method in both cases of small and large radius.A detailed analysis on each term of these formulas is given.
