Measurement of pi^-p-->pi^0 n in the vicinity of the eta threshold
We report a new measurement of the differential cross section for pi^-p-->pi^0 n from p_pi=649 to 752 MeV/c, which is around the opening of the eta channel (685 MeV/c). Our data support the main features of the pi^-p charge-exchange differential cross sections generated by the SAID piN partial-wave analysis. The opening of the eta channel has a clear effect on the shape of the excitation function for dsigma (pi^-p-->pi^0 n), which is most noticeable in the backward direction.
