Description
The possibilities of photonuclear experiments at $E_\gamma = (1–4)$ MeV on collimated gamma-sources from Compton backward-scattering of laser radiation on beams of accelerated electrons are considered. The following items are discussed: operation parameters of such gamma-sources; monitoring of their gamma-beams; types of possible photonuclear experiments, including nuclear resonance fluorescence ones (see, e.g., [1]), total absorption ones using transmission method (see, e.g., [2]), and especially experiments on inelastic scattering of gamma-quanta with population of metastable states of nuclei. As an example, for the last case, there are considered cross-sections of the reaction $^\mathrm{115g}$In ($\gamma$, $\gamma’$) $^\mathrm{115m}$In ($E_{exc} = 336$ keV; T$_{1/2}$ = 4.486 h) in dependence on $E_\gamma$ obtained: a – in [3]; b – in [4] (see fig. 1).
