摘要：

An unsuccessful search has been made for the reaction π-p → pF p ̄n to find an M- state in p̄n corresponding to the M0 (2020) and M0 (2204) found earlier in the baryon exchange process π-p → Δ0 (or N0 (1520)) + M0. From this negative result, it is concluded that the previous reaction proceeds mainly by nucleon exchange and it is suggested that the NN̄ coupling for the M0 is more important than the Δ̄N coupling. Some indications are also given for the NN̄ mode as the main decay mode for these M0 states. © 1979.
