Phase-shift analysis of 3He(d, d)3He scattering

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.
