Baryon spectroscopy at existing and future hadron facilities

It is shown that measurements of the spin rotation parameters in np elastic scattering allow to remove discrete ambiguities in a partial-wave analysis and, hence, to get a unique solution. Recent results obtained in experimen ts at ITEP accelerator are presented, and perspectives of further measureme nts are discussed. Another valuable contribution to the spectroscopy of nonstrange baryons com es from extensive investigation of pi(-)p reactions with neutral particles in the final state. Two complementary programs of studying pi(-)p reactions with neutral particles in the final state are now underway at the accelera tors of PNPI and BNL. A brief description of experimental setups and exampl es of obtained results are given.
