低能区的^16O＋^12C散射折叠模型研究

Folding Model for ^(16)O+^(12)C Scattering at Lower Energy Region

基于12C和16O原子核的α粒子结构,利用α粒子折叠模型对较低能区的16O+12C弹性散射进行了研究计算。计算结果表明,α粒子折叠模型能较好地描述低能区的16O+12C弹性散射角分布实验数据。折叠模型光学势的虚部对小射角区影响很小,但对大射角区的截面计算有一定的影响。

The ^16O＋^12C elastic scattering at lower energy region has been analyzed by using an α folding potential based on the a-particle structure model of ^16O and ^12C nuclei. The main features of the measured ^16O＋^12C scattering angular distributions can be reasonably described. The imaginary part of the optical potential has a certain effect on the calculated cross sections for the larger scattering angular region.
