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 R ₁= Ξ(1530)/ Ξ, R ₂=Σ(1385)/Σ(1385) and R ₃=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.
- hadronization,
- spin suppression,
- flavor conservation,
- excited baryons
