The low energy 2H(α, αp)n reaction

Abstract An investigation of the breakup reaction 2 H(α, αp)n with incident energies of α-particles between 9.847 and 13.991 MeV has been performed. Results from kinematically complete measurements at 21 different kinematical configurations are presented. Final-state interaction enhancements have been experimentally observed. The energy is sufficiently low that the A = 6 system should be reasonably well described as a three-body system. The experimental data were compared with predictions based on Faddeev equations. Taking into account that no adjustable parameter is used, the quality of agreement is in general acceptable.

Intermediate mechanisms in fission-like fragmentation in the 32S + 59Co and 32S + 63Cu reactions

Abstract The fission-like fragmentation of the 32 S + 59 Co and 32 S + 63 Cu composite systems has been studied at incident energies E / A ≈ (4–5) MeV/nucleon. Mass, energy and angular distributions of the fission-like fragments were obtained from time-of-flight measurements. The mean total kinetic energies of the fragments are found to be fully relaxed, whereas a strong angular dependence is observed in the mass distributions. The data are interpreted in terms of a dynamical model based on the transport theory.
