Abstract

Data for the $α$ -particle pickup reaction ( $d$ , ${}^{6}{Li}$ ) have been obtained at 35-MeV bombarding energy for even-even nuclei from ${}^{12}C$ to ${}^{238}U$ . The cross sections for the transitions to the ground states decrease approximately as $\frac{1}{{A_{t}}^{3}}$ where $A_{t}$ is the target mass. $α$ -particle transfer probabilities have been extracted from the data and are found to be substantially enhanced in heavy nuclei away from shell closures, particularly for deformed nuclei near $A \approx 150$ . $α$ -particle correlations appear to be related to two-nucleon pairing effects.
