本文报道了吡嗪弹性电子散射的新测量结果。用交叉电子-分子束光谱仪结合相对流技术，测量了散射电子角范围10°-129°，能量范围3-50 eV的七个离散能量下的绝对微分截面（DCS）。积分弹性截面随后从这些DCS数据在每个能量。在可能的情况下，本文的结果和那些从复杂的Schwinger多通道和R-矩阵计算之间的比较，一般相当好的定量雅阁被发现。最后，为了更好地研究一些丰富的共振结构的理论预测，弹性电子激发函数的结果。
We report on new measurements for elastic electron scattering from pyrazine. Absolute differential cross sections (DCSs) at seven discrete energies in the range 3-50 eV, and over the scattered electron angular range 10°-129°, were determined using a crossed electron-molecular beam spectrometer in conjunction with the well-established relative flow technique. Integral elastic cross sections were subsequently derived from those DCS data at each energy. Where possible comparison between the present results and those from sophisticated Schwinger multichannel and R-matrix computations is made, with generally quite good quantitative accord being found. Finally, in order to better study some of the rich resonance structure predicted by theory, results from elastic electron excitation functions are presented.
