The nucleon-antinucleon cross sections at 167 Mev have been computed with two complex potential well models. Yukawa shaped complex wells were first studied in Born approximation. A semi-theoretical poteniial has then been analyzed on the digital computer IBM 704: the real part is the Signell and Marshak potential, adapted to the nucleon-antinucleon problem, and the imaginary part, a Yukawa phenomenological well. In order to account for the experimental results (large total cross-section and small scattering cross section), it appears necesssrt to choose a weak real potential to the usual nuclear force range. The fixed source meson theory leads to a real potential, which is much too strong and does not predict an imaginary potential at all; this theory cannot account for the experimental results. (auth)
