Nucleon-antinucleon potential parameters from the Ramsauer effect in\(\bar pp\) low-energy scatteringlow-energy scattering

  • P. P. Delsanto

We investigate the possible existence of a Eamsauer effect in\(\bar pp\) scattering at very low energies. If detectable, this effect allows the determination of the range and depth of the nucleon-antinucleon interaction. Some numerical results are derived from a simple model.
