Abstract

The excitation energy above the breakup threshold of the alpha+ d/Li-6 system, after the interaction of Li-6 nuclei with a Pb-208 target, was deduced from the invariant mass of the alpha + d system. Data were collected with a large-solid-angle detector set-up at four beam energies around the Coulomb barrier. The excitation of the Li-6 nucleus above the breakup threshold (1.47 MeV) has a quite similar behavior at each measured beam energy and angle; it is peaked at similar to1 MeV above the threshold and shows an exponential decay on the high energy side, which is a clear signature of a direct breakup process. The experimental excitation energies are reproduced both in shape and absolute value by 1) fully quantum-mechanical Coupled-Channel calculations with coupling to discretized-continuum Li-6 excitations, 2) semi-classical Coupled-Channel approach, where the relative motion is treated along a classical trajectory.
