摘　　要：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 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[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.
