Abstract

The Trojan Horse Method has been applied to study the Li-7(p, alpha)(4) He and Li-6(d, alpha)(4) He reactions through the Li-7(d, alphaalpha)n and Li-6 (Li-6, alphaalpha)(4) He three body processes, respectively. The electron screening potential deduced from these experiments is much larger than the adiabatic approximation prediction for both cases; the systematic discrepancy between data and theoretical predictions is thus confirmed. Astrophysical implications of these measurements are also discussed.
