摘要

The spectrum of nucleon resonances is essential for our understanding of structure and component of nucleon,but our knowledge of them with the mass of around 2.0 GeV is still far from complete.The main reasons are that many resonances are emerging and several reaction channels are opening in this energy region.Theη′N production threshold is about 1.89 GeV so it is a good place for studying the high lying resonances.For instance,we can use this reaction to search for the P13(1900)state close to the threshold,which is unfavored by qudrk-diquark models[1],but predicted in the conventional constitute quark models[2].
