Abstract：
We use a simple decay model of low excited baryon states to evaluate the decay contributions of these states to the (1/2)⁺ and (3/2)⁺ baryons. we further input the experiment values R₁=(1530)/Ξ, R₂=∑(1385 )/∑and R₃=∧(1520)/∑(1385)at γ on c.m. energy and use the basic relations derived in the precious paper todetermine the total production rates of the low excited baryons of various SUf(3)multiplets.
