Lowest-energy broad α-cluster resonances in ¹⁹F

NUCLEAR REACTIONS ⁴He(¹⁵N, α), E=21 MeV; measured reaction products, light recoils, α particles, excitation functions by the thick target inverse kinematic (TTIK) method at the DC-60 facilities at Nur Sultan-Kazakhstan. ¹⁹F; analyzed present data and previous experimental data for resonances in ¹⁹F from ¹⁵N(α, α) reaction using R-matrix method with AZURE code; deduced resonance parameters and spectroscopic factors from fits to experimental data; calculated energies and resonance parameters using configuration interaction methods with FSU interaction Hamiltonian, and compared with experimental data. Complete analysis of 50 resonances in ¹⁹F given in authors' companion article: 2022Go03: Phys. Rev. C 105, 014615 (2022).
