| contents | Extensive data of antiproton scattering cross sections with protons and nuclei have advanced our understanding of hadronic interactions with antinucleons. However, low-energy antineutron scattering data are scarce, thereby limiting our understanding of the S-wave antinucleon-nucleon and antinucleon-nucleus interactions. We present a novel production scheme of extremely low-energy antineutrons that could remedy this situation. This method is based on backward charge-exchange reaction ($p\bar{p}\to n\bar{n}$), and can reach the lowest momentum of 9 MeV/c, which would be well suited to study of the S-wave antinucleon-nucleon or antinucleon-nucleus interactions. |
