摘要
We derive the separate helicity amplitudes using the partial wave analysis in the process of pseudo-scalar meson photoproduction.For J^P= 3/2^+,we find the amplitude is model independent.According to parity conservation,the general amplitude in the case of J^P=1/2 is obtained.We prove this general amplitude corresponds to the situation of λ=-1 when adopting the circular polarization.Finally,the formulas of scattering amplitudes involving the meson photoproduction with J^P= 3/2^+ are obtained from the chiral quark model.
