Abstract
Targets of and have been bombarded by 35 MeV/nucleon ions. Inside a cone of ±10° around the beam axis, outgoing protons and α particles were detected by an arrangement of 18 scintillators in coincidence with particles of charge Z=5–11 emerging at 2°. At this energy the identified reaction mechanisms differ significantly from the ones observed in the 10–15 MeV/nucleon region. Important energy transfer of around 50 MeV to the target-like residues is observed. For the coincident oxygen-α events, in addition to the well-known sequential decay mechanism of the projectile, about 40% of the events are attributed to another mechanism producing oxygen ions narrowly peaked near the beam velocity. Among the other reaction channels, cases are present which can be interpreted in terms of sequential decay alone, as well as others where admixtures of different processes play a role.
