用延迟电位飞行时间（RP-TOF）方法测量了0.7-400 eV正电子和1.400eV电子与CH_4、C_2 H_4和C_2 H_6分子碰撞的总截面。通过归一化方法而不是绝对测量获得横截面。这些碳氢化合物的正电子散射总截面的最小值明显地显示在从4到5 eV的区域。与这些碳氢化合物的电子碰撞的总截面与以前的数据和正电子碰撞数据进行了比较。
Total cross sections for 0.7-400 eV positrons and 1.400 eV electrons colliding with CH4, C2H4 and C2H6 molecules have been measured using a retarding potential-TOF (RP-TOF) method. The cross sections were obtained by a normalisation method rather than absolute measurements. The minima of the total cross sections for positron scattering by these hydrocarbons were distinctly shown in the region from 4 to 5 eV. The total cross sections for electron collisions with these hydrocarbons were compared with previous data and with positron collision data.
