In a recent experiment investigating the origin of the α particle yield in the 7Li + 144 Sm system the measured α+ d coincidences at a bombarding energy of 30 MeV were shown to arise from decay of the 2.186-MeV 3 + resonance of 6Li. In this work we demonstrate that the laboratory frame α particle angular distribution extracted from these data can be well described by a standard coupled channels Born approximation calculation and, furthermore, that the mechanism is dominated by direct, one-step single neutron stripping to the 3 + resonance, as shown previously for the 7Li + 65Cu and 93Nb systems.

Abstract
In a recent experiment investigating the origin of the α particle yield in the 7Li + 144 Sm system the measured α+ d coincidences at a bombarding energy of 30 MeV were shown to arise from decay of the 2.186-MeV 3 + resonance of 6Li. In this work we demonstrate that the laboratory frame α particle angular distribution extracted from these data can be well described by a standard coupled channels Born approximation calculation and, furthermore, that the mechanism is dominated by direct, one-step single neutron stripping to the 3 + resonance, as shown previously for the 7Li + 65Cu and 93Nb systems.File in questo prodotto:
