Abstract
We demonstrate a new approach to the analysis of extensive multienergy data. For the case of d + He-4, we produce a phase shift analysis cov ering the energy range 3-11 MeV. The key idea is the use of a new tech nique for data-to-potential inversion which yields potentials that rep roduce the data simultaneously over a range of energies. It thus effec tively regularizes the extraction of phase shifts from diverse, incomp lete, and possibly somewhat contradictory data;sets. In doing so, it w ill provide guidance to experimentalists as to what further measuremen ts should be made. This study is limited to vector spin observables an d spin-orbit interactions. We discuss alternative ways in which the th eory can be implemented and which provide insight into the ambiguity p roblems. We compare the extrapolation of these solutions to other ener gies. Majorana terms are presented for each potential component.
