| 摘 要： | 考虑核间相互作用,利用修正的库仑玻恩模型(MCB-PT)计算了入射能量为16 MeV 的O7+碰撞氦单电离的全微分截面，并将计算结果与最近的实验数据和三体库仑波(3C)模型及含核间相互作用的连续扭曲波程函初态 (CDW-EIS-PT)模型所得结果进行了比较，发现MCB-PT理论结果在中间动量转移条件下binary峰的位置与实验结果符合得很好，且位于动量转移的方向上。此外,分析了扭曲效应对全微分截面的影响，表明随着动量转移的增加,扭曲效应更加明显。

| Abstract: | The modified-Coulomb-Born with internuclear interaction (MCB-PT) model is used to calculate fully differential cross section (FDCS) for helium single ionization by 16-MeV O7+ impact in the scattering plane. Comparisons are made with experimental data and other theories from the three-Coulomb (3C) wave and the distorted-wave eikonal-initial-state with internuclear interaction (CDW-EIS-PT). We find that angular location of the binary peak is in good agreement with experiment at intermediate momentum transfer. Furthermore, we also assess the influence of distorting effect on the FDCS and find that the distorting effects play a significant role with increasing momentum transfer. |
