Investigation of secondary γ-ray angular distributions using the ¹⁵N(p, α₁γ)¹²C^* reaction

NUCLEAR REACTIONS ¹⁵N(p, αγ)¹²C^*, E=0.88-4.0 MeV; measured Eγ, Iγ, angular distributions using Hybrid Array of LaBr₃(Ce) Gamma Ray Detectors (HAGRiD) at the 5-MV Santa Ana accelerator of University of Notre Dame; deduced σ(E), σ(θ) distributions. ¹⁵N(p, αγ)¹²C^*; ¹²C(α, α), (α, α'); analyzed present and previous experimental data for σ(θ) distributions by R-matrix formalism using AZURE2 code. Discussed inconsistencies and difficulty in fitting previous data. Detailed cross section data for both the reactions listed in the Supplemental Material.
