Spin-dependent part of $\bar{p}d$ interaction cross section and Nijmegen potential
interaction cross section Nijmegen potential
2011/7/21
Low energy $\bar{p}d$ interaction is considered taking into account the polarization of both particles. The corresponding cross sections are obtained using the Nijmegen nucleon-antinucleon optical pot...
