Comparison of model-independent optical potential analyses

Conference paper
Part of the Lecture Notes in Physics book series (LNP, volume 236)

Abstract

Analysing α−40Ca scattering data at Eα = 104 MeV a comparison is made between different model-independent optical potential descriptions. In particular the Fourier-Bessel expansion and the inverse Bargmann fit are considered. The ill-posed nature of optical potential analyses is studied showing the necessity of regularisation procedures. With the statistical regularisation apriori knowledge about the potential can be taken into account in the analysis in a consistent way. Although nearly unconstrained parametisations of the local optical potential or the S-matrix are used there remains a remarkable bias due to the specific ansatz.
