Integral cross sections of photonuclear reactions near the giant dipole resonance

The total cross sections of (γ, n) reactions were measured for 12 nuclei from⁴⁵Sc to²⁰⁸Pb using an activational method on bremsstrahlung from a microtron with maximum energy 25 MeV. Calculations of the total cross sections were performed on the basis of a modified preequilibrium decay model. Good agreement was obtained between the experimental and computed cross sections in the mass number range 100–208. 1 figure, 3 tables, 13 references.
