【 摘 要 】

We present comprehensive experimental measurements of double differential cross sections (DDCS) for atmospheric gases, Ar, N2, CO2and CH4. DDCSs were obtained by measuring the energy and angular distributions of one of the two outgoing electrons which are indistinguishable by use traditional electron spectrometer with an electron analyzer.
