Resumen en inglés Differential and integral cross sections for elastic scattering of electron by NH3 molecule are investigated for the energy ranging from 10 eV to 20 keV. The calculations are carried out in the framework of partial wave formalism, describing the target molecule by means of one center molecular Hartree-Fock functions. The potential used includes a static part -obtained here numerically from quantum calculation- and fine effects like correlation, polarization and exchange potentials. The results obtained in this model point out clearly the role played by the exchange and the correlation-polarization contributions in particular at lower scattering angles and lower incident energies. Both differential and integral cross sections obtained are compared with a large set of experimental data available in the literature and good agreement is found throughout the scattering angles and whole energy range investigated here
