Phys. Rev. A 60, 1199–1205 (1999)Cross sections and polarization fractions for elastic e--O2 collisionsReceived 4 February 1999; revised 30 March 1999; published in the issue dated August 1999 The Schwinger variational iterative method and the distorted-wave approximation are combined to study elastic electron scattering by O2 for incident energies ranging from 5 to 500 eV. Differential, integral, and momentum transfer cross sections as well as polarization fractions are reported. A complex optical potential, which accounts for the static, exchange, correlation-polarization, and absorption contributions is used to describe the electron-molecule interaction. Comparison of our calculated results with experimental and other theoretical results is encouraging. © 1999 The American Physical Society URL:
