On activation studies of photonuclear reactions on γ-beams from backward Compton scattering at E ≤ 40 MeV

Abstract

For photonuclear research with γ-quanta having energies Eγ ≤ 40 MeV at the source under developing with backward Compton scattering of laser radiation on accelerated electrons, activation experiments are proposed as initial ones. These experiments are important both for developing techniques for tuning and monitoring such γ-beams, and for studying the excitation of pygmy and giant resonances in nuclei at Eγ near the threshold of the (γ, n) reaction, as well as the multiplicity of photoneutrons during deexcitation of giant resonances at Eγ above the threshold of (γ, 2n)-reaction.
