Hall Identifying Long-Sought 18F(p,α)15O Resonances Affecting γ-Ray Emission from 18F in Novae 2019 .txt text/plain 280 12 53 Because models don't reproduce observed nova properties, the successful detection of keV−MeV energy γ rays would provide further constraints on nova models. Annihilation radiation, which is produced via e+-e− annihilation, should be the most intense source of γ rays from the explosion. cache/79407w6567z.txt txt/79407w6567z.txt
