The scattering length for electron-argon scattering is calculated very accurately by an ab initio method with wave functions computed exactly at zero energy. The multiconfiguration Hartree-Fock method, which takes into account the effects of target polarization and electron correlation through the configuration-interaction procedure, is used for the calculation. The differential, total, and momentum-transfer cross sections are also calculated for very low energies ranging from 0-1 eV. The present result for the scattering length is found to be in excellent agreement with the experimental results of Buckman and Lohmann [J. Phys. B 19, 2547 (1986)] and Haddad and O'Malley [Aust. J. Phys. 35, 35 (1982)].
