Abstract：
Based on the statistical theory and available measured isomeric cross section ratio, a systematic formula of the isomeric cross section ratio with one parameter for neutron induced reactions was developed. This formula is applicable for the mass region 44≤A≤197,spin region of isomeric and ground states 0≤J_m≤12 and 0.5≤J_g≤8 of the residual nucleus, respectively. Fair agreement was obtained between the systematics predictions and measurements. Within the range of nuclides and spins the systematics predictions can provide useful isomeric cross section ratio information where experimental data are of large discnepancy or where experimental data are not available.
