Abstract

A part in understanding the nucleosynthesis of heavy nuclei is a proper description of the effective interaction between an alpha-particle and a target nucleus. Information about the so-called alpha + nucleus optical-model potential is achieved by precise cross-section measurements at sub-Coulomb energies aiming to constrain the theoretical models for the nuclear physics input-parameters. The cross sections of the Cd-108(alpha, gamma) and Cd-108(alpha, n) reaction have been measured for the first time close to the astrophysically relevant energy region via the in-beam method at the high-efficiency gamma-ray spectrometer HORUS and via the activation technique at the Cologne Clover Counting Setup at the Institute for Nuclear Physics in Cologne, Germany. Comparisons between experimental results and theoretical predictions calculated in the scope of the Hauser-Feshbach statistical model confirm the need for a exponentially decreasing imaginary part of the potential. Moreover, it is shown that the results presented here together with already published data indicate that a systematic investigation of the real part of the potential could help to further improve the understanding of reactions involving alpha-particles.
