Abstract
We measured the , , and reactions at low energies using the thick target inverse kinematics method, with a polyethylene target and a radioactive beam available at the Radioactive Ion Beams in Brazil facility of São Paulo. By measuring simultaneously several reaction channels , , and , the still uncertain high-lying resonances of , close to the proton threshold, can be studied and their parameters, such as energy, width, and spin parity can be more reliably determined. The experimental excitation functions of the reactions , , and were analyzed using the -matrix theory, which allows us to infer the properties of the resonances. Multichannel -matrix analysis provides evidence for a significant clustering in the channel. The experimental data and the multichannel -matrix analysis will be presented.
