摘要
采用Ｈａｒａｆｒｅｅ－ｅｌｅｃｔｒｏｎ－ｇａｓｅｘｃｈａｎｇｅａｐｐｒｏｘｉｍａｔｉｏｎ（ＨＦＥＧＥ）交换势和本文作者提出的极化势，用等效势模型计算了能量在０．１３６－１２ｅＶ内的ｅ－－Ｏ弹性散射总截面和动量转移截面，结果与Ｔｈｏｍａｓ和Ｎｅｓｂｅｔ的理论计算结果以及实验结果作了比较。
Using the effective potential model including the Hara free- electron - gas exchange approximation to the exchange potential and our modified polarization pot6ntial, the elastic toeal and momentum transfer cross sections are computed for the low - energy (0. 136eV≤ E≤12eV) election scattering from the ground state of oxygen. The results are in agreement with the calculation of thomas and Nesbet. The total cross sections are in reasonable agreement with theexperiments.
