Abstract：
The photonuclear reaction cross sections of giant dipole resonances for ²⁰⁸Pb,¹⁸⁶W,¹⁸¹Ta,¹⁷⁵Lu,⁷⁵As and ⁵⁵Mn are calculated by using the extended exciton model in a further approximation.They are in good agreement with experimental data.The theoretical framework being given in our previous paper is reasonably supported.
