Fourier-bessel-analysis of alpha-particle scattering optical potentials and nuclear matter densities
Elastic scattering cross sections of 104 MeV alpha-particles from 40,48Ca were analyzed using a Fourier-Bessel-series description of the real optical potential and also using density dependent folding models with Fourier-Bessel expansions of the nuclear matter densities. The uncertainties in the derived parameters are discussed for the real potentials and nuclear densities, respectively, as a function of radius and additionally for integral quantities such as volume integral, root-mean-square radius or higher moments. It is shown that the errors of the radial form factors are more realistic as compared to model descriptions using e.g. squared Saxon-Woods form-factors. The analyses yield for the nuclear matter rms radii rm(48) − rm (40) = 0.12 ± 0.07 fm.
