We present a way of using numerical quadrature in momentum space for solving the three-dimensional Lippmann-Schwinger equation. The integration is performed in spherical coordinates. Test calculations show that the quadrature is well suited for the electron-molecule scattering problems. Sample results of elastic scattering of electrons are presented for the empirical Yukawa potential and ab initio Hartree-Fock potential of the hydrogen and methane molecules.
