Abstract：
The purpose of this paper is to study, the A-N interaction by using meson exchange theory. We have considered three processes: ⅰ) Single K meson exchange, ⅱ) Box diagrams of 2π and πρ exchanges with a nucleon in the intermediate states, and ⅲ) Box diagrams of 2π and πρ exchange with an isobar in the intermediate states. For simplicity, two approximations are used in the calculation. First, the initial nucleon N and hyperon are considered to be at rest. Second, an average value is used for the energies of the intermediate states. The results are qualitatively consistent with experiments.
