Fragment mass distributions of 238U fission by deuterons with the energy of 37 MeV

Fragment mass distributions of 238U fission by deuterons with the energy 37 MeV measured by the γ-spectrometry method on the U-240 cyclotron of INR National Academy of Sciences of Ukraine are given. Fragment mass distribution has an asymmetric form. The thin structure corresponding to the fission product yields with masses of 104, 111, 126, 132 a. e. m. was observed

Cross sections of the 3H(d, 3He) nn reaction at the deuteron beam energy 37 MeV

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
