用能量范围为10-300 eVlab的F ~+离子束研究了F ~++CO体系中的电荷转移反应。通过A→X跃迁的发射观察到电子激发产物CO+（A2 i）.在低碰撞能量下，主要产物在振动能级v '= 5中。在12 eVc. m时，反应截面σ（5）约为1 A2。并且随着碰撞能量的增加而减小。在v '= 5处的大截面可以通过近共振电荷转移反应来解释。产物的旋转温度约为300 K，这是反应物CO气体的温度。对于共振电荷转移，平动能是无效的，但电子能和振动能彼此强烈耦合。
Charge transfer reactions in the F++CO system were investigated using a F+ ion beam in the energy range 10–300 eVlab. The electronically excited product CO+ (A 2Πi) was observed by the emission from the A→X transitions. At low collisional energy the dominant product is in the vibrational level v’=5. The reaction cross section σ(5) is about 1 A2 at 12 eVc.m. and decreases with increasing collision energy. The large cross section at v’=5 can be interpreted by near resonant charge transfer reactions. The rotational temperature of the product is about 300 K, which is the temperature of the reactant CO gas. For the resonant charge transfer, the translational energy is not effective, but the electronic and vibrational energy couple with each other strongly.
