我们已经测量了（e，2 e）三重微分截面（TDCS）的电子碰撞电离苯酚与共面不对称运动学的入射电子能量为250 eV。当入射电子分别以-5度、-10度和-15度角散射时，获得了20 eV处慢出射电子的角分布的实验测量。的TDCS数据进行了比较与分子三体扭曲波模型内进行的计算。在这种情况下，一个混合水平的协议，这是依赖于被探测的运动学条件，观察到的理论和实验结果之间的二元峰区域。在所有运动学条件下的反冲特征的实验强度相对较小，但理论计算仍然大大低估了。(C)2014 AIP Publishing LLC.
We have measured (e, 2e) triple differential cross sections (TDCS) for the electron-impact ionisation of phenol with coplanar asymmetrical kinematics for an incident electron energy of 250 eV. Experimental measurements of the angular distribution of the slow outgoing electrons at 20 eV are obtained when the incident electron scatters through angles of -5 degrees, -10 degrees, and -15 degrees, respectively. The TDCS data are compared with calculations performed within the molecular 3-body distorted wave model. In this case, a mixed level of agreement, that was dependent on the kinematical condition being probed, was observed between the theoretical and experimental results in the binary peak region. The experimental intensity of the recoil features under all kinematical conditions was relatively small, but was still largely underestimated by the theoretical calculations.
