Structure Studies with Low-energy Radioactive Beams from TwinSol: Resonant scattering and (α,n) reactions using Active Targets*

Various emergent structures such as clustering in light unstable nuclei can have a  great influence on reaction observables such as resonant scattering, (α,n) and radiative capture reactions. At the University of Notre Dame., we use TwinSol, a pair of superconducting solenoids to produce a number of light radioactive beams to study such reactions in conjunction with active target detectors. This allows for the measurement of cross sections with low beam rates and outgoing particles with low energies. We will present the search for cluster structure in light unstable nuclei in ¹⁴O using resonant alpha scattering. This includes results of the resonant scattering analysis and future work to extend this analysis to study (α,n) reactions, which may have an influence on light-element radiative capture cross sections that are important for the production seed nuclei in various r-process scenarios. The possibility of measuring radiative capture cross sections directly will also be presented.
