Study of reaction cross-sections of astrophysical interest
We aim to infer radiative-capture cross sections at low energy employing an indirect technique by using MESA’s high-intensity electron beam to induce photo-dissociation reactions of astrophysical interest, such as (γ, α) and (γ, n). Since photo-dissociation and radiative capture are time-reversed processes, their cross sections are directly related. By measuring the electron with the high-resolution MAGIX spectrometers in coincidence with the recoil particles, the background contributions can be significantly reduced. These new measurements will challenge nuclear theory calculations. For this purpose, dedicated theoretical efforts will aim at modelling these reactions.
