摘要：
The S factor and the fusion cross-section values for the C-12 + C-12 reaction are evaluated in the framework of a simple barrier-penetration model, which takes into account quadrupole and hexadecapole surface deformations of C-12. The calculated values agree well with corresponding experimental data at off-resonances energies. It is shown that the strong oblate quadrupole deformation of C-12 induces the increasing of both the S factor and the fusion cross-section values at subbarrier energies. The S factor and the fusion cross section for the C-12 + C-12 reaction are slightly reduced at low energy due to the influence of the hexadecapole deformation.
