Study of the 18F(p,α)15O reaction for application to nova γ-ray emission

Abstract The 18 F(p,α) 15 O reaction is recognized as one of the most important reaction for nova gamma-ray astronomy as it governs the early ≤ 511 keV emission. However, its rate remains largely uncertain at nova temperatures due to unknown low-energy resonance strengths. In order to better constrain this reaction rate, we have studied the one-nucleon transfer reaction, D( 18 F,pα) 15 N, at the CRC-RIB facility at Louvain La Neuve.
