摘要：

States in 19Ne above the 15O + α threshold were populated by means of the 19F(3He,t)19Ne* reaction, and their alpha-particle decays to the 15O ground state were measured. The branching ratios Γα/Γtotal for the Ec.m. = 850-, 1020-, 1971-, 1183- and 1563-keV resonances in 19O + α were determined. This information together with alpha-particle and/or gamma-ray partial widths (determined from knowledge of these quantities for the mirror states in 19F) determines the strengths of these 15O(α,γ)19Ne resonances and the 15O(α, γ)19Ne reaction rate for temperatures between 7 × 108 and3 × 109K. © 1990.
