The 15 O(α,γ) 19 Ne reaction is an important trigger reaction leading to the rapid proton ( rp ) capture process in X-ray bursts. The primary uncertainty in determining its astrophysical rate is the uncertain α branching ratios of levels near E x = 4.1 MeV in 19 Ne. These states have been populated in a study of the 20 Ne( p, d ) 19 Ne reaction, and α branching ratios are reported in this manuscript.
