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 ${}^8$B on ${}^{58}$Ni and ${}^{208}$Pb 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 $80^{\circ }$ in the one-step calculation for ${}^{58}$Ni, virtually disappears.
