Description

A two-pion-exchange three-body force (3BF) is derivaded and calculated its contribution to the trinucleon ground state. The Hyperspherical Harmonic method has been used. Coulomb and 3BF have been treated nonperturbatively. Results show sensitivity to the short range part of the force. A comparative study is made with other forms of 3BF found in the literature.

Abstract (Portuguese)

Uma forca de tres corpos (3BF), tipo troca de dois pions, e derivada e calculada sua contribuicao para o estado fundamental de tres nucleons. O metodo dos harmonicos hiper-esfericos e usado. Forcas Coulombiana e de tres corpos tem sido tratadas nao perturbativamente. Resultados mostram-se sensiveis a parte de curto alcance da forca. Um estudo comparativo e feito com outras formas de 3BF achadas na literatura. (Autor)
