We have measured cross sections for single capture, transfer ionization, single ionization, double ionization, ionization excitation, and transfer excitation for fully stripped oxygen projectiles at energies between 8 and 20 MeV on D{sub 2} molecular targets. Coincidences between charge-analyzed projectiles and recoil D{sup +} and D{sub 2}{sup +} products were measured. The time of flight (TOF) of the recoil, collected by applying an extraction electric field, was used to separate the D{sup +} from D{sub 2}{sup +} ions. TOF spectra taken with no field were used to distinguish the D{sup +} ions from different dissociative channels, including the electronically excited 2{ital p}{sigma}{sub {ital u}},2{ital s}{sigma}{sub {ital g}},2{ital p}{pi}{sub {ital u}} channels and the double-ionization channel. The results are compared with two model calculations.
