Abstract：
We use a simple decay model for the lowest excited baryons to evaluate their decay contributions to the ground states. We further input the experimental data R₁=Ξ(1530)/Ξ, R₂=Σ(1385)/Σ(1385) and R₃=λ(1520)/Σ(1385) at γ(1S) resonance and use the basic relations derived in the previous paper to determine the total production rates of the lowest excited baryons of various SU_f(3) multiplets.
