| Popis: | Inclusive 3He spectra and differential cross sections of the 3H(d,3He)nn reaction measured at the deuteron beam energy of 37 MeV are presented. The shape of the inclusive 3He spectra can be reproduced by using a model that takes into account neutron - neutron Final State Interaction, Sequential Decay of the 4He* resonance (Ex = 21,2, Γ = 0,7 MeV) and an interference of resonant amplitude and Watson - Migdal as well. Thus this way differential cross sections of the 3H(d,3He)nn reaction followed by appearance of singlet nn pairs and angular distribution of singlet dineutrons are obtained. The results are compared to the supermultiplet potential model of the lightest nuclei interaction. |
