The elastic and one-pion production channels from the pp interaction at four c.m. energies between 2150 and 2240 MeV are described. No evidence of formation of the narrow T(2195) meson is observed. The elastic differential cross section is measured in the range of squared four-momentum transfer ¦t¦ > 0.03 GeV2. This has been extrapolated to the forward direction where Re/Im parts of the amplitude are deduced. The one-pion final states are well described by assuming that they are dominated by Δ-production.
