Using a fast neutron time-of-flight spectrometer the angular distributions of seven neutron groups leading to the ground state and the 1.63, 4.25, 4.97, 5.63, 5.80 and 6.75 MeV levels of Ne 20 have been measured at mean deuteron energies of 2.51, 2.61, 3.04 and 3.31 MeV. Only the neutron group to the 6.75 MeV level shows a clear stripping pattern at all energies, and it can be fitted with l = 0. The other angular distributions vary rapidly with energy and cannot be explained by plane wave stripping. The dimensionless stripping reduced width of the 6.75 MeV level at a bombarding energy of 3.31 MeV is θ 2 = 0.012. It is compared to the theoretical predictions of the unified model, along with the results of other experimenters.

The differential cross sections of the 12 C(d, n 0 ) 13 N and the 12 C(d, p 0 ) 13 C reactions have been measured in the deuteron energy range from 2.7 to 3.2 MeV. The data could be fitted assuming a direct and a single resonance amplitude. The parameters of the compound resonance are consistent for both reactions. For the 12 C(d, n 0 ) reaction the analysis gives Γ = 65±10 keV, E R = 3.02±0.02 MeV and for the 12 C(d, p 0 ) reaction Γ = 77±10 keV and E R = 3.01±0.02 MeV.

Angular distributions of 13 neutron groups from the reactions Be9(d, n)B10, B10(d, n)C11 and B11(d, n)C12 to the ground state and the 0.72, 1.74, 2.15 and 3.58 MeV levels of B10, to the ground state and the 2.00, 4.32, 4.81 and 6.35/6.49 MeV levels of C11, and to the ground state and the 4.43 and 7.66 MeV levels of C12 have been measured for at least four bombarding energies between 1.1 and 3.2 MeV. Differential yield curves have been obtained at 30° and 120° for the reactions Be9(d, n)B10 and B11(d, n)C12 in steps of approximately 30 keV. Most of the measured angular distributions change slowly with bombarding energy; this indicates that the direct amplitude is still important even at low bombarding energies. A comparison with (d, p) reactions to charge conjugate states shows a close similarity in the angular distributions of the corresponding (d, n) and (d, p) reactions.
