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Murray[1]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。

In the frame of standard first-order distorted-wave Born approximation ( DWBA) , the triple differ-ential 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 experi-mental data of Nixon and Murray[1]. 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.
