The effective range theory is developed for electron-hydrogen scattering. The scattering length a 8 and the effective range r0, of the singlet state are determined by making use of the accurate solu tion of the H- ion state, as a,=7.03, r08 =3.37 (in atc?mic unit). The scattering length a1 and the effective range r01 of the triplet state are calculated from the zero energy solution by a variation-perturbation method. The results are a1 =2.3.4, r01 =1.29.
