Multi-step effects in subcoulomb breakup
Abstract
Following earlier one-step calculations, we explore the contributions of multi-step effects for the breakup of low energy 8B on 58Ni and 208Pb within a coupled discretised continuum channels (CDCC) formalism. The Coulomb multi-step differential cross section is significantly reduced for all angles, the largest effect being the destructive interference of nuclear couplings. The nuclear peak, at around 80 in the one-step calculation for 58Ni, virtually disappears.
