DYNAMICS OF CHEMICAL-REACTIONS OF DOUBLY-CHARGED IONS - CF2D-2( FORMATION IN COLLISIONS OF CF22+ AND D)

The dynamics of the formation of the chemical rearrangement product CF 2D+ and the charge transfer product CF2+ in collisions of the dication CF22 with D-2 was investigated in a crossed-beam scattering experimen t at a collision energy of 0.6 eV (c.m.). The scattering diagrams obta ined show that both products are formed in impulsive processes in whic h Coulomb repulsion between two singly charged products, CF2D+ + D+ an d CF2+ + D-2(+), respectively, plays a dominant role. The energy parti tioning of the total energy available in these highly exoergic process es is about half in the relative translation and about half in the int ernal energy (electronic and/or vibrational).
