Role of projectile resonances on breakup and fusion cross sections in the [formula omitted] reaction

Abstract

We investigate qualitative and quantitative projectile resonance effects on breakup and total fusion cross sections of the breakup of 6Li on 144Sm target. We show that these resonances exhibit opposite and slightly pronounced effects on the integrated breakup cross sections than on total fusion cross sections. It is obtained that, for energies above the Coulomb barrier, breakup cross sections are increased by the inclusion of these resonances, while fusion cross sections are reduced. We deduced that, on average, above the barrier, breakup cross sections are increased by ∼10%, whereas fusion cross sections are suppressed by ∼4% in the presence of the resonances.
