共面双对称几何条件下Ne原子(e,2e)反应的三重微分截面

利用标准一阶扭曲波玻恩近似方法(DWBA)计算了共面双对称几何条件下不同能量电子碰撞电离Ne原子的三重微分截面(TDCS),与Nixon和Murray1]最新的实验测量数据进行比较.当入射电子能量较低时,理论计算结果和实验数据符合较差;而随着入射电子能量的增加,符合程度逐渐改善.

Triply differential cross-sections for (e,2e) process of Ne in the coplanar double-symmetric geometry

In the frame of standard first-order distorted wave Born approximation (DWBA), the triple differential cross sections (TDCS) of single ionization of Ne atoms were calculated in the coplanar double-symmetric geometry by different energies electron impact. The calculated results were compared with the recently experimental data of Nixon and Murray. When the incident electron energies are very low, the theoretical calculation results are in poor agreement with the experimental data; with the increase of the incident electron energy, the degree of coincidence is improved.
