Accurate ab-initio calculation of scattering length, total and Momentum-transfer cross sections is performed for low-energy elastic scattering of electrons from open-shell sulfur atom. The polarization of the sulfur atoms due to the scattered electron and the electron correlation effects that are very important in the calculation are taken into account through the configuration interaction procedure using the multiconfiguration Hartree-Fock method for electron-atom scattering. The elastic differential, total elastic and momentum-transfer cross sections for low energies ranging from 0 - 27.2 eV are obtained from phase shifts for various partial waves calculated in this approximation. The present results will be compared with the available experimental and other theoretical results.
