摘      要：A new empirical formula has been developed that describes the（7,n nuclear reaction cross sections for isotopes with Z ≥ *** results were supported by calculations using TALYS-1.6 and EMPIRE-3.2.2 nuclear modular *** energy region for incident photon energy has been selected near the giant dipole resonance（GDR peak *** evaluated empirical data were compared with available data in the experimental data library *** data produced using TALYS-1.6 and EMPIRE-3.2.2 are in good agreement with experimental *** have tested and presented the reproducibility of the present new empirical *** observe the reproducibility of the new empirical formula near the GDR peak energy is in good agreement with the experimental data and shows a remarkable dependency on key nuclei properties：the neutron,proton and atomic number of the *** behavior of nuclei near the GDR peak energy and the dependency of the GDR peak on the isotopic nature are *** effort has been made to explain the deformation of the GDR peak in（γ,n nuclear reaction cross sections for some isotopes,which could not be reproduced with TALYS-1.6 and *** evaluated data have been presented for the isotopes ^180W,^183W,^202Pb,^203Pb,^204Pb,^205Pb,^231Pa,^232U,^237U and ^239Pu,for which there are no previous measurements.
