Sensitivity of the ¹³C(α, n)¹⁶O S factor to the uncertainty in the level parameters of the near-threshold state

NUCLEAR REACTIONS ¹³C(α, n)¹⁶O, E(cm)<1.2 MeV; calculated astrophysical S factors and reaction rates by R-matrix theory using the AZURE2 code for different sets of level parameters for the near-threshold 1/2+ resonance at 6356 keV in ¹⁷O; analyzed theory and available experimental data to investigate the sensitivity of the low-energy extrapolation to the associated uncertainties and discrepancies. Relevance to s process in asymptotic giant branch (AGB) stars and i process in carbon-enhanced metal-poor (CEMP) stars.

Backscattering measurement of ⁶He on ²⁰⁹Bi: Critical interaction distance

NUCLEAR REACTIONS ²⁰⁹Bi(⁶He, ⁶He), E=12, 14, 16 MeV, [secondary ⁶He beam from ²H(⁷Li, ⁶He), E=32 MeV]; measured ⁶He spectra using silicon ΔE-E telescope, σ(θ, E) at the TwinSol facility of Notre Dame Nuclear Structure Laboratory; deduced ratio of elastic to Rutherford cross sections. Comparison with a three-body CDCC calculation, and with experimental data for ²⁰⁹Bi(α, α), (⁶Li, ⁶Li), (⁹Be, ⁹Be), (¹²C, ¹²C), (¹⁶O, ¹⁶O), and ²⁰⁸Pb(⁶He, ⁶He) reactions.
