    The cross sections for the reactions (γ, n) leading to the ground and isomeric 1h 11/2 states in 16 isotopes of Pd, Cd, Sn, Te, Ba, Ce, Nd, and Sm are measured. The energy of γ rays corresponds to the region of the giant dipole resonance. The method of induced activity is used in the measurements. It is found that isomeric ratios depend on the number of intranuclear neutrons and protons and on the excitation energy of a residual nucleus. Various factors that affect the isomeric ratio are discussed.
