Abstract

At 3 GeV/c, the total and differential cross sections of the reactions K^-n → Yπ^- have been determined for nine S = -1 baryonic states. Backward peaks associated with a dip near u = -0.2 are observed in many cases. They have been interpreted, for the isospin-zero Y-states, in terms of a proton-exchange mechanism. The backward peaks in the reactions K^-n → Λπ^- and K^-n → Σ^oπ^- have been more quantitatively related to the backward πN → Nπ differential cross sections at the same energy. This comparison leads to the conclusion, that the first reaction is dominated by nucleon exchange, whereas the second one requires a more complex exchange mechanism.
