The elastic (3)He+d cross section of relevance for knock-on effects in radio frequency heated ((3)He)D plasmas

The cross section for d+He-3 elastic scattering has been determined for the angular range 20-180 degrees (CM) for beam energies E-d = 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 (He-3)D plasmas subjected to RF heating and their manifestations in the spectrum of the d + d fusion neutron emission are discussed.
