摘要

The Trojan Horse Method has been applied to study the ⁷Li(p, α)⁴He and ⁶(Li(d, α)⁴He reactions through the ⁷Li(d, αα)n and ⁶Li(⁶Li, αα)⁴He 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.
