Title:
Measurement of electron capture and ionization cross sections for D_{2} in collision with fast O^{8+} ions
Abstract:
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_{2} molecular targets. Coincidences between charge-analyzed projectiles and recoil D^{+} and D^{+}_{2} products were measured. The time of flight (TOF) of the recoil, collected by applying an extraction electric field, was used to separate the D^{+} from D^{+}_{2} ions. TOF spectra taken with no field were used to distinguish the D^{+} ions from different dissociative channels, including the electronically excited 2p sigma_{u}, 2s sigma_{g}, 2p pi_{u} channels and the double-ionization channel. The results are compared with two model calculations.
