By fitting the s-wave partial amplitudes for pi -N scattering in an unphysical region, the energy range is greatly extended over which the contribution from the process pi + pi yields N + N may be examined. The method detects contributions from this process in states of isotopic spin T = 0 and T = 1. The energies t1/2 are estimated for which this process is important. The form of these contributions is as expected from considerations of angular momenta. Estimates of the amplitudes for pi + pi yields N + N are deduced. The T = 0 amplitude is large, but in the T = 1 case the amplitude is much smaller than the values predicted from the nucleon isovector form factors. (auth)
