Abstract
A phase shift analysis of pi N scattering has been carried out at 18 d iscrete energies in the region 160-600 MeV. Charge splitting of the P- 33 phase shift (similar or equal to 2 degree) is observed with a chang e of sign at similar or equal to 350 MeV and vanishing at similar or e qual to 600 MeV. Marked deviations from an earlier analysis are found for S and P-amplitudes as a result of using new precision data and an untraditional method of the analysis.
