用修饰的库仑波(MCB)模型计算入射能量2MeV/amu裸碳离子碰撞氦单电离的全微分截面,并将计算结果与相应的实验数据和其他理论结果进行比较,发现MCB理论在较小的电离电子能量和较大的动量转移条件下与实验结果符合得很好,在动量转移比较小时MCB理论结果binary峰的位置向大角方向发生了偏移。MCB理论和3CW(三体库仑波)理论相似,他们都比3DW-EIS(三体扭曲波程函初态近似)理论符合的好,说明了在微扰势中被动离子与入射粒子的相互作用是不可忽略的。与3CW理论相比,MCB模型在初态波函数和相互作用势中加入扭曲效应,比较发现扭曲效应会影响全微分截面的大小,但影响不是很明显。
The modified MCL model was used to calculate the full differential cross section of the incident single ionized helium ion with an incident energy of 2MeV / amu. The calculated results were compared with the corresponding experimental data and other theoretical results. Ionized electron energies and large momentum transfer conditions agree well with the experimental results. When the momentum transfer is relatively small, the position of the binary peak of the MCB theoretical result shifts to a larger angle. The MCB theory is similar to the 3CW (Three Body Coulomb Wave) theory, and they are all in good agreement with the 3DW-EIS theory. It shows that the interaction of passive and incident particles in perturbation potential is not Ignored. Compared with 3CW theory, MCB model adds distorting effect in initial state wave function and interaction potential. It is found that distorting effect will affect the size of full differential cross section, but the effect is not obvious.
