Abstract: Inclusive 3H spectra and dσ(ϑ, E)/dΩdE differential cross sections of the 3H(d, t) reaction are measured at the deuteron beam energy of 36.9 MeV. Shapes of the inclusive 3H spectra were reproduced by using a model that takes into account simple quasi-binary mechanisms and characteristics of the experimental method, i.e., nonmonochromaticity of the accelerated deuteron beam, target thickness, spectrometer energy resolution, beam spot size on the target, detector apertures, and target-detector distance. It is found that the most important processes in the 3H(d, t) reaction are the proton-neutron Final State Interactions in the singlet 1S0 state (singlet deuteron) and in the triplet 3S1 one, sequential decay via the 4H* resonance (Ent = 2.2 MeV, Γ = 3.4 MeV) and the proton (neutron) - triton quasifree scattering processes.
Keywords: deuteron, 37 MeV, triton, differential cross sections, simulation.
