摘要：
The photoproduction of nucleon resonances is calculated based on a chiral constituent quark model including both relativistic corrections H-rel and two-body exchange currents, and it is shown that these effects play an important role. We also calculate the first moment of the nucleon spin structure function g(1)(x,Q(2)) in the resonance region, and obtain a sign-changing point around Q(2)similar to0.27 GeV2 for the proton.
