      abstract     = {The single-pion production reactions pp -> d pi(+), pp ->
                      np pi(+) and pp -> pp pi(0) were measured at a beam momentum
                      of 0.95 GeV/c (T-p approximate to 400 MeV) using the short
                      version of the COSY-TOF spectrometer. The central
                      calorimeter provided particle identification, energy
                      determination and neutron detection in addition to
                      time-of-flight and angle measurements from other detector
                      parts. Thus all pion production channels were recorded with
                      1-4 overconstraints. The main emphasis is put on the
                      presentation and discussion of the npp+ channel, since the
                      results on the other channels have already been published
                      previously. The total and differential cross-sections
                      obtained are compared to theoretical calculations. In
                      contrast to the pp pi(0) channel we observe in the np pi(+)
                      channel a strong influence of the Delta excitation. In
                      particular, the pion angular distribution exhibits a
                      (3cos(2) circle minus + 1)-dependence, typical for a pure
                      s-channel Delta excitation and identical to that observed in
                      the dp+ channel. Since the latter is understood by a
                      s-channel resonance in the D-1(2) pn partial wave, we
                      discuss an analogous scenario for the pn pi(+) channel.},
