| Abstract: | Inclusive spectra and differential cross sections of the 3H(d, 3He)nn reaction, measured at E d = 36.9 MeV are presented. The shape of 3He spectra was reconstructed by modeling amplitudes of the neutron-neutron final state interaction (Watson-Migdal amplitudes), sequential decay via the 4He* resonance (E* = 21.2 MeV, Γ = 0.7 MeV), and their interferences. The model allowed the determination of the angular dependence of the differential cross section of the 3H(d, 3He)nn reaction accompanied by singlet nn-pair production. The results are compared to the supermultiplet potential model of the lightest nuclei interaction. |
