Resonant Structure Described by a Deep Folded Rotential for the ^12C＋^12C Scattering at Lower—Energy Region

Based on the analyses of the elastic angular distributions,an energy-dependent folding potential for the ^12C+^12C system is established.This potential has a deep real part,and can reasonably well describe the resonant structure in the ^12C+^12C elastic scattering in the low-energy region of 10-70MeV.
