Abstract

The two-step process of transfer followed by breakup is explored by measuring a rather complete set of exclusive data for reaction channels populating states in the ejectile continua of the ⁷Li+⁹³Nb system at energies close to the Coulomb barrier. The cross sections for \ensuremathα+\ensuremathα events from one proton pickup were found to be smaller than those for \ensuremathα+d events from one neutron stripping and \ensuremathα+t events from direct breakup of ⁷Li. Coupled-channels Born approximation and continuum-discretized coupled-channels calculations describe the data well and support the conclusion that the \ensuremathα+d and \ensuremathα+\ensuremathα events are produced by direct transfer to unbound states of the ejectile.
