Abstract:

By fitting the s-wave partial amplitudes for N scattering, in an unphysical region, we have greatly extended the energy range over which we can examine the contribution from the process N N. Our method shows up contributions from this process in states of isotopic spin T 0 and T 1. We can estimate the energies t12 for which this process is important. The form of these contributions is just what would be expected from considerations of angular momenta. Estimates of the amplitudes for N N are deduced. The T 0 amplitude is large, but in the T 1 case the amplitude is much smaller than the values which were predicted from the nucleon isovector form factors. Author
