Bayesian estimation of the S factor and thermonuclear reaction rate for ¹⁶O(p, γ)¹⁷F

NUCLEAR REACTIONS ¹⁶O(p, γ), E=0.002-2.5 MeV; analyzed data from several studies, analyzed S-factors by Bayesian R-matrix fit; calculated astrophysical S-factor, thermonuclear astrophysical reaction rates (range 0.003-3.5 GK). R-matrix approximation with Bayesian model. Single-particle model employing a Woods-Saxon potential.

Thermonuclear fusion rates for tritium + deuterium using Bayesian methods

NUCLEAR REACTIONS ³H(d, n), E=5-270 keV; compiled data from several studies, analyzed S-factors by Bayesian R-matrix fit; calculated astrophysical S-factors using the single-level, two-channel approximation, marginalized posterior of the S-factor, S-factor normalization factors, densities for the electron screening potential, thermonuclear reaction rates for temperatures of 0.001 to 1.0 GK, and reactivities for kT=0.2 to 50.0 keV. R-matrix approximation with Bayesian model. Relevance to future commercial fusion reactors, and Big Bang nucleosynthesis.
