Abstract
The energy and angular distribution of the ionic products from the reaction F+(D2,D)FD+ were measured as a function of primary ion energy ranging from 0.7 to 12.5 eV in the laboratory system. At the low energies the distribution showed a high degree of symmetry although some forward peaking was detectable. At the higher energies the distribution was asymmetric relative to ±90° indicating that the reaction was proceeding by an impulsive direct mechanism. A study of the exoergicity as a function of projectile energy shows that the bulk of the exothermicity of the reaction is converted into vibrational energy in the product ion. Failure to observe the reaction F+(D2,FD)D+ was attributed to a violation of the spin and symmetry conservation rules.
