Astrophysical S_E2 factor of the ¹²C (α, γ)¹⁶O reaction through the ¹²C(¹¹B, ⁷Li)¹⁶O transfer reaction

NUCLEAR REACTIONS ¹²C(¹¹B, ⁷Li), (¹¹B, ¹¹B), E=50 MeV; ¹⁶O(⁷Li, ⁷Li), E=26 MeV; measured charged-particle spectra, differential σ(θ) using the Q3D magnetic spectrograph at the HI-13 tandem accelerator of the CIAE-Beijing. ¹²C(α, γ), E(cm)<5 MeV; deduced astrophysical S_E2(300) factor of the ground state. ¹⁶O; deduced asymptotic normalization coefficient (ANC) and reduced α width of the 6.917-MeV level from finite-range distorted wave Born approximation (FRDWBA) and coupled-reaction-channel (CRC) analysis using FRESCO code. Comparison with previous experimental values, and with theoretical model predictions. R-matrix analysis of scattering data.
