The level structure of 20Na and the impact upon the stellar reaction rate for 19Ne(p, γ)20Na
1990
Abstract The level structure of 20 Na up to 3.6 MeV excitation energy has been investigated via the 20 Ne( 3 He, t) 20 Na charge exchange reaction. The observed bound and unbound states are discussed in terms of the analog structure of the A = 20, T = 1 triplet. The partial widths of the unbound levels have been calculated to derive the resonance strengths of these states in the 19 Ne(p, γ) 20 Na reaction channel. The stellar reaction rate for 19 Ne(p, γ) 20 Na has been calculated and is compared with previous estimates.
