On Activation Studies of Photonuclear Reactions on \({\gamma}\)-Beams from Backward Compton Scattering at \(\boldsymbol{E}_{{\gamma}}\boldsymbol{\leq 40}\) MeV

Proposed as initial activation experiments for photonuclear research with \(\gamma\)-quanta at energies \(E_{\gamma}\leq 40\) MeV are those using a source of backward Compton scattered laser radiation on accelerated electrons, which is currently under development. These experiments are crucial both for refining the techniques of tuning and monitoring such \(\gamma\)-beams, and for investigating the excitation of pygmy and giant resonances in nuclei at \(E_{\gamma}\) near the threshold of the (\(\gamma,n\)) reactions, as well as the multiplicity of photoneutrons during the de-excitation of E1 giant resonances at \(E_{\gamma}\) above the threshold of the (\(\gamma,2n\)) reactions.
