Resumo

An optical model analysis of the available data for A = 8 (He-8, Li-8 and B-8) projectiles on different targets with light, medium and heavy mass has been performed. A systematic potential set based on a Woods-Saxon Potential shape was obtained. This potential describes the elastic scattering angular distributions quite well. A more physical model within the framework of a semi-microscopic (a)pproach, where the nuclear matter density distributions of the B-8, 8Li and He-8 projectiles have been calculated by using a microscopic self-consistent relativistic mean field (RMF) theory, was also considered. The agreement of the calculated angular distributions with the data was reasonable. An improvement of the agreement could be achieved by changing the imaginary diffuseness parameter, which is a sensitive parameter in these calculations. (AU)
