Abstract

The reaction 7Li(d, nα)4He has been studied detecting neutron-alpha coincidences. The energies of the detected particles were determined by means of time-of-flight measurement for neutrons and a silicon, surface-barrier detector for alphas. Simultaneously alpha-alpha coincidences from 7Li(d, αα)n were detected using two solid-state detectors. The measurements were performed at bombarding energies from 2.6 to 4.0 MeV in steps of 0.2 MeV. In addition the reaction 7Li(d, αα)n was studied separately at 4.0 and 9.0 MeV for several angular settings of the two solid-state detectors. The most important reaction mechanism is found to be sequential decay through intermediate 5He and 8Be states.
