Reliability of the double-folding potential for fusion cross sections of light systems

We study the fusion reaction of light systems with one-dimensional barrier penetration model using the α-α double-folding cluster (DFC) potential. We especially analyze the fusion cross sections of the 12C + 12C, 16O, 24Mg, 28Si, 16O + 16O, 24Mg + 24Mg, 28Si, and 28Si + 28Si reactions. The results...
