Description

The effects of virtual Coulomb excitation of giant multipole resonances as well as of relativity on sub-barrier elastic scattering of heavy-ions are investigated. Closed expressions for the effect of giant quadrupole and octopole excitation from the adiabatic polarization potential, on the elastic scattering differential cross section, are derived. Comparison with optical model and coupled channels calculations is reported.The effect of special relativity on the Rutherford cross section is also described in a closed form. (Author)

Abstract (Portuguese)

Investigam-se os efeitos da excitacao coulombiana virtual das ressonancias de multipolos gigantes tanto quanto da relatividade sobre o espalhamento elastico de sub-barreira de ions pesados. Derivam-se expressoes fechadas para o efeito de excitacao octopolar e quadrupolar gigante a partir do potencial de polarizacao adiabatico sobre a secao de choque diferencial de espalhamento elastico. Relata-se a comparacao com os calculos de modelos oticos e de canais acoplados. Descreve-se tambem o efeito da relatividade especial sobre a secao de choque de Rutherford numa forma fechada. (L.C.)
