100MeV/amu C6+ 碰撞氦原子单电离的全微分截面
Fully differential cross section for single ionization of helium by 100 MeV/amu C6+ impact

利用修正的库仑玻恩近似理论（MCBPT和MCB）计算了散射平面和垂直平面内100MeV/amu C6+ 单电离氦原子的全微分截面，研究了核核作用对截面的影响.其结果与实验数据和3DW理论进行了比较.发现，对于小动量转移，MCBPT计算结果与实验符合的很好；对于大动量转移，MCB结果很好的反映了实验数据.而且，我们详细的分析了扭曲势效应对截面的影响，结果表明随着动量转移的增加扭曲势效应迅速增强.
The modified Coulomb-Born approximation is applied to calculate the fully differential cross section (FDCS) for single ionization of helium by 100 MeV/amu C6+ impact. We study the effects of the internuclear interaction on the FDCS in the scattering plane and the perpendicular plane. Comparisons are made with absolute experimental data and the 3DW results and we find that our calculations with (without) the internuclear interaction yield excellent agreement with experiments for the small (large) momentum transfer. Furthermore, the influence of the distorting potential effects on the FDCS is discussed. It turns out that the distorting potential effects become significantly important with increasing momentum transfer.
