Dissociative electron attachment to the reactive C(2)F(5) molecular radical has been investigated with two complimentary experimental methods; a single collision beam experiment and a new flowing afterglow Langmuir probe technique. The beam results show that F(-) is formed close to zero electron energy in dissociative electron attachment to C(2)F(5). The afterglow measurements also show that F(-) is formed in collisions between electrons and C(2)F(5) molecules with rate constants of 3.7 × 10(-9) cm(3) s(-1) to 4.7 × 10(-9) cm(3) s(-1) at temperatures of 300-600 K. The rate constant increases slowly with increasing temperature, but the rise observed is smaller than the experimental uncertainty of 35%.
已用两种互补的实验方法（单分子束实验和新型流动后余晖兰缪尔探针技术）研究了活性 C(2)F(5)分子自由基的离解电子俘获。束实验结果表明，在 C(2)F(5)的离解电子俘获中，F(-)在接近零电子能量下形成。余晖测量也表明，在电子与 C(2)F(5)分子之间的碰撞中形成 F(-)，在 300-600 K 的温度下，速率常数为 3.7×10(-9)至 4.7×10(-9)cm(3)s(-1)。速率常数随温度缓慢增加，但观察到的增加小于 35%的实验不确定度。
