We use a momentum-dependent optical model potential to analyze the annihilation cross sections of antineutron $\bar n$ on C, Al, Fe, Cu, Ag, Sn, and Pb nuclei for projectile momenta $p_{\rm lab}$ $\lesssim$ 500 MeV/$c$. We obtain good…

Background: A recent coupled reaction channel (CRC) study shows that the enhanced oscillation of the elastic $^{16}$O+$^{12}$C cross section at backward angles is due mainly to the elastic $\alpha$ transfer or the core exchange. Such a…
