Breakup Processes in the Systems⁹Be+²⁰⁸Pb,²⁰⁹Bi and⁶Li+²⁰⁸Pb around the Coulomb Barrier

Abstract

From recent experimental data for the systems 9Be+208Pb,209Bi and 6Li+208Pb it results that the complete fusion process is hindered with respect to realistic theoretical predictions (CCFUSS). However the 9Be+208Pb,209Bi complete fusion cross sections are different from each other contrary to expectations. The 6Li data show breakup of the projectile into two outgoing fragments, well reproduced by CDCC approach, as well as α or deuteron capture from the target; this is relevant for the theories on the reaction dynamics around the Coulomb barrier.
