| Abstract: | The cross section for d+3He elastic scattering has been determined for the angular range 20-180° (CM) for beam energies Ed = 0.05 to 11 MeV through combined use of experimental data, Coulomb scattering and extrapolations. The results are used to study, for instance, how the cross section is affected by nuclear interaction contributions. Implications of these results on the calculation of knock on effects in (3He)D plasmas subjected to RF heating and their manifestations in the spectrum of the d + d fusion neutron emission are discussed. |
