Optical and Coupled-Channels Description of ²⁰Ne+¹⁶O Elastic Scattering

Role of α-Cluster Transfer in the Formation of 20Ne + 16O Cross-Sections at Backward Angles

“…Secondly, the potential itself may be phenomenological optical potential (OP) or a more microscopic potentials such as double folding potential (DFP) and cluster folding (CF) potential. 16 O( 20 Ne, 16 O) 20 Ne is an example for elastic transfer which was extensively studied before [9][10][11][12][13][14][15][16] and the contribution of α-cluster transfer is observed in formation the cross sections at backward angles, such effect is well known as "Anomalous large angle backscattering" (ALAS).…”

“…[14], the gross structure observed in the 20 Ne+ 16 O angular distributions was analyzed using a deep optical potential. N. Burtebayev et al [15] tried to reproduce the experimental data for 20 Ne+ 16 O at E lab =50 MeV, the data was analyzed using deep real potential with a sum of Woods-Saxon typed surface and volume imaginary potentials. All these previous studies constructed the interaction potential on a phenomenological basis.…”

Measurements of the Elastic and Inelastic Scattering Cross Sections of 13C Ions on 12C Nuclei at the Near Coulomb Barrier Energy

“…In this context, study of the cross sections in this area is of great interest for astrophysics since it allows us to estimate cross sections of the possible radiative capture 12 С(n, ) 13 С reaction and its role in the evolution of the Universe immediately after the Big-Bang. Some of the key reactions for the carbon and oxygen burning stages are 12 C+ 12 C [1], 12 C+ 16 O [2,3] and 16 O+ 20 Ne [4] leading to a synthesis of more heavy nuclei. From the angular distribution of the experimental data the spectroscopic factor can be extracted for the 13 C → 12 C + n vertex which is valuable for the 12 С(n, ) 13 С reaction.…”
