Underground study of the ¹⁷O(p, γ)¹⁸F reaction relevant for explosive hydrogen burning

NUCLEAR REACTIONS ¹⁷O(p, γ)¹⁸F, E(cm)=160-370 keV; measured Eγ, Iγ, on- and off-resonance γ spectra, γ-branching ratios from decay of resonances, half-life using activation method at underground LUNA accelerator at Gran Sasso National Laboratory; deduced S factors for secondary transitions, total S factor, resonance strength, astrophysical S factor and reaction rates. ¹⁸F; deduced levels, analysis of astrophysically important 183-keV resonance. Comparison with previous experimental results. ¹⁵N, ^18,19F, ¹⁸O; evaluated abundances by Nova model calculations.

RADIOACTIVITY ¹⁸F(β⁺)[from ¹⁷O(p, γ), E(cm)=160-370 keV]; measured Eγ, Iγ, half-life.
