Study of α-16O scattering by orthogonality condition models
Description
The use of approximate microscopic theories in α-16O scattering is investigated. The Orthogonality Condition Model (OCM) with the direct potential of the Resonating Group Method (RGM) and with an effective local potential V sub(eff') derived from Kernels of the Generator Coordinate Method (GCM) is employed to study collisions at CM energies up to 30 MeV, for all relevant partial waves. Although the predictions of the OCM are consistent with 'exact' RGM results in both cases, the nuclear phase-shifts obtained with the effective potential are better. It is noticed the presence of ambiguities in the derivation of V sub(eff'). The nature of such ambiguities is discussed. (Author)

Investiga-se o uso de teorias teorias microscopicas aproximadas no espalhamento α-16O. Emprega-se o Modelo de Condicao de Ortogonalidade (MCO) com o potencial direto do Metodo de Grupo Ressonante (MGR) e com um potencial local efetivo V sub(eff), derivado de nucleos do Metodo de Coordenadas Geradoras para estudar colisoes a energias de centro de massa ate 30MeV, para todas as ondas parciais relevantes. Embora as previsoes do MCO sejam consistentes com os resultados do MGR 'exato' nos dois casos, os deslocamentos de fases nucleares obtidos com o potencial efetivo sao melhores. Notou-se a presenca de ambiguidades na derivacao de V sub(eff). Discute-se a natureza de tais ambiguidades. (L.C.)Files
