测量的2 +和N2O态激发的相对电子微分截面（dcs） (Marinkovic et al . 1986 J. Phys。B:。通过最近的前向散射函数对广义振荡器强度进行了归一化。利用电子分子束交叉排列的电子能谱仪，分别在15、20、30、50和80 eV的电子冲击能下进行了测量。根据动量色散法的解析特性，在零散射角处和接近零散射角处对测量数据进行校正。该状态的绝对DCS值与唯一可用的理论数据集进行了比较，而2 +状态的结果是首次提出的。
The measured relative electron differential cross sections (DCSs) for excitation of the 2 + and states of N2O (Marinkovic et al 1986 J. Phys. B: At. Mol. Phys. 19 2365) have been normalized through a recent forward scattering function for the generalized oscillator strength. Measurements were obtained at electron impact energies of 15, 20, 30, 50 and 80 eV, using the electron spectrometer with crossed electron-molecule beam arrangement. Measured data are corrected at and near zero scattering angles following the analytic behaviour of the momentum dispersion method. Absolute DCS values for the state are compared with the only available set of theoretical data, while for the 2 + state results are presented for the first time.
