Title in Portuguese
Estudo da matriz-S do espalhamento entre íons pesados
Keywords in Portuguese
Espalhamento
Íons pesados
Abstract in Portuguese
Neste trabalho, o problema do espalhamento entre íons leves-pesados é abordado principalmente do ponto de vista da matriz-S. Desenvolvemos um método que permite a obtenção dos elementos da matriz-S do espalhamento elástico e seus respectivos erros diretamente a partir de distribuições angulares. Analisamos dados experimentais dos sistemas 12C+160 e 12C+24Mg em baixas energias. Investigamos uma possível extensão analítica da matriz-S para o plano complexo com base na Teoria Algébrica do Espalhamento dentro da simetria S0(3, 1 ). O problema de canais acoplados também é abordado nesta teoria.

Abstract in English
In this paper, the problem of light-scattering between heavy ions is mainly addressed from the viewpoint of the matrix S. We have developed a method that allows obtain the S-matrix elements of the elastic scattering and their errors directly from the angular distributions. A summary of experimental data 12C + 12C and 160 + 24mg in low power systems. We investigated a possible extension of analytic S-matrix for the complex plane Based on Algebraic Theory of Scattering inside the symmetry S0 (3, 1). The problem coupled channels is also addressed in this theory.
