Abstract

Complete angular distributions of the differential cross section and all four deuteron-analyzing powers for ³He(d, d)³He scattering have been measured at 14 energies between 1.5 and 11.5 MeV. For all components the major changes in the observables occur below 7 MeV deuteron energy.

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

For all higher energies, the extension was made by normalizing the coulomb angular dependence at the lowest measured angle of the data at each energy. We have found six references of which five [9–13] were used in the data base of 21 different projectile energies in the range Ed = 0.325 to 11.5 MeV as summarized in Table 1. The covered angular ranges varied with energy and was typically limited to θCM ≈ 40–130° for Ed ⩽ 1.5 MeV but increased with energy to cover the range θCM ≈ 10–170° at Ed = 11.5 MeV.
The cross section for d+³He elastic scattering has been determined for the angular range 20–180° (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 (³He)D plasmas subjected to RF heating and their manifestations in the spectrum of the d + d fusion neutron emission are discussed.
The elastic scattering of polarized 3He by 2H at 22.5, 24, 27, 30 and 33 MeV
2000, Nuclear Physics A
The angular distributions of the analysing power and the relative cross-sections for the elastic scattering of polarized $^{3} He$ nuclei by $^{2} H$ have been measured at incident $^{3} He$ energies of 22.5, 24, 27, 30 and 33 MeV. The data, considered in terms of fitted Legendre polynomials, clearly show a structure near 30 MeV $^{3} He$ energy which is more striking for odd L coefficients. In addition, our data, along with other data on the differential cross sections and on the analysing power for the scattering of polarized $^{2} H$ , have been analysed for the phase shifts and mixing parameters in the S-matrix description. The phase shifts selected are compared with those from resonating-group theory calculations. The prominent residual differences were attributed to further resonances which involve the formation of $^{5} Li$ nuclei at high excitation energy. Finally a level scheme is compared with the predictions of a multi-particle, multi-shell model calculation.

Phase-shift analysis of d-α elastic scattering between 3 and 43 MeV
1983, Nuclear Physics, Section A
Phase shifts for the d-α elastic scattering have been extracted from differential cross sections and the vector and tensor analyzing powers of $^{4} He(d, d)^{4}$ He scattering in the energy range from 3 to 43 MeV. The analysis includes spin-orbit splitting, mixing of states and absorption to reaction channels. A new parametrization of two-channel scattering matrices is given and compared. Excellent fits have been obtained with a new phase-shift code ONEZERO, which is capable of taking into account all degrees of freedom in strong interactions. The Argand-plot method has been used for resonance analysis of the excited ⁶Li system. Five new broad T = 0 resonances above 15 MeV deuteron energy have been found in ⁶Li, corresponding to D₃, F₂, F₃, G₃ and G₄ resonant states. Problems from phase-shift ambiguities are pointed out.
Phase-shift analysis of 3He(d, d)3He scattering
1980, Nuclear Physics, Section A
Between 0.32 and 5.0 MeV deuteron energy a phase-shift analysis of ³He(d, d)³He crosssection and deuteron analyzing-power data has been made. Expressions relating the analyzing powers to the scattering amplitudes are derived and an energy-independent parametrization of threechannel scattering matrices is given. The analysis includes spin-orbit splitting, mixing of states and loss of flux to reaction channels. Excellent fits have been obtained. However, the data set has proved to be too incomplete to permit a unique determination of the relevant parameters. At low energies continuum ambiguities have been found and explored. Common properties of the solutions point to the existence of several broad highly excited states of the ⁵Li nucleus.
