Coulomb barrier penetrability in the 11Be + 208Pb breakup reaction

Abstract

We use the continuum discretized coupled channels method to study the 11Be+208Pb breakup reaction. We investigate the effects of the continuum–continuum couplings (ccc) on the breakup cross sections. We find that high partial waves strengthen the ccc. Using the breakup cross sections of this reaction, we analyze the penetrability of the Coulomb barrier and show that this penetrability is reduced when the ccc are included.
