A competition of the low-energy Coulomb excitation (CE) with the compound nucleus (CN) formation in α-induced reactions below the Coulomb barrier has recently been assumed in order to make possible the description of the latter as well as the α-particle emission by the same optical model (OM) potential. However, we show in the present work that the corresponding partial waves and integration radii provide evidence for the distinct account of the CE cross section and OM total-reaction cross… 


α-particle optical potential tests below the Coulomb barrier
The results of two recent papers concerning ({alpha},{gamma}) and ({alpha},n) reaction cross sections close to the reaction thresholds are discussed with regard to predictions of a recent
α-particle nuclear surface absorption below the Coulomb barrier in heavy nuclei
An analysis of all available alpha-particle-induced reaction cross sections on nuclei within the mass number range 121<=A<=197, below the Coulomb barrier, is carried out. This analysis leads to an
Direct study of the α -nucleus optical potential at astrophysical energies using the Zn 64 (p,α) Cu 61 reaction
In the model calculations of heavy element nucleosynthesis processes the nuclear reaction rates are taken from statistical model calculations which utilize various nuclear input parameters. It is
