Our results, using 10-fs, 790-nm pulses, suggest that a large peak at low kinetic energy release is associated with the D+ + D2 dissociation channel of D3+. The most likely dissociation pathways leading to two-body breakup of D3+ are identified with additional measurements using 25-fs, 790-nm and 40-fs, 395-nm pulses. We also show that the slow D+ + D2 dissociation dynamics can be manipulated by the pulse duration.© American Physical Society (APS). This Item is protected by copyright and/or related rights.
