Abstract
The recent experimental data obtained by the OBELIX Collaboration on total and annihilation cross sections are presented and analysed in terms of scattering length approximation. This analysis allowed the evaluation of the partial wave contributions to the np interaction as well as the isospin dependence in the NN total cross sections, but the most striking result is the indication of a quite unexpected, narrow structure just above the NN threshold.
