Abstract：
Whether the degree of freedom of isospin states in highly excited compound nucleus is conservative or not gives the information of Coulomb interaction which affects the decay property of compound nucleus.The isospin dependent level decay widths of ³⁰P are calculated by means of H.A.Weidenmuller's statistical theory.It takes the isospin coupling coefficients into account for transmission coefficients as well as for the total number of decay channels.This is the difference from that of Hauser-Feshbach formula.
