23Na(p,a)20Ne Marshall et al. 2023 Utilizing the high-resolution capabilities of the TUNL SPS, astrophysically important excited states in 24Mg were populated via the (3He, d) transfer reaction. Astrophysically relevant states in 24Mg between 11 < Ex < 12 MeV were studied using high-resolution magnetic spectroscopy. In particular, careful calibration and compilation of previous results give… Continue reading 23Na(p,a)20Ne

18O(p,a)15N Bruno et al. 2019 Nuclear reaction rate based on low-background direct measurement performed at the Laboratory for Underground Nuclear Astrophysics (LUNA) from center of mass energy 𝐸c.m.=340 keV down to 𝐸c.m.=55 keV. The strength of a key resonance at center of mass energy 𝐸𝑟=90 keV was found to be a factor of 10 higher than previously reported. Link to the paper. Nuclear… Continue reading 18O(p,a)15N

17O(p,a)14N Bruno et al. 2016 Thermonuclear reaction rate based on a new direct determination of the ER=64.5  keV resonance strength performed at the Laboratory for Underground Nuclear Astrophysics (LUNA). Link to the paper. Nuclear reaction rate in the MESA format:

27Al(p,a)24Mg La Cognata et al. 2022 A new rate of the 27Al(p,a)24Mg reaction. Strengths of the levels in the reaction were first determined via the indirect trojan horse method, and then used to calculate the reaction rate with RatesMC. Link to the paper
