我们报道了在高强度（约108 W cm-2）二氧化碳激光存在下，氦和氩在8-20 eV范围内通过10度-140度散射角散射电子的微分截面的实验测量。大多数报告的结果都是在通常应用于这类测量的Kroll-Watson近似预测为零截面的条件下从氩散射出来的。报告的截面范围约为适当的无场弹性散射截面的12%，与理论预测严重不符。
We report experimental measurements of the differential cross sections for scattering of electrons in the range 8-20 eV from helium and argon through scattering angles of 10 degrees -140 degrees in the presence of a high intensity ( approximately 108 W cm-2) carbon dioxide laser. The majority of the results reported are scattering from argon under conditions for which the Kroll-Watson approximation, usually applied to these types of measurements, predicts zero cross sections. The cross sections reported range up to approximately 12% of the appropriate field-free elastic scattering cross sections in strong disagreement with the theoretical predictions.
