Measurement of ³⁹K(p, γ)⁴⁰Ca resonance strengths below 900 keV for nucleosynthesis in classical novae

NUCLEAR REACTIONS ³⁹K(p, γ)⁴⁰Ca, E=0.4, 1.4 MeV; measured Eγ, Iγ; deduced resonance strengths, astrophysical reaction rate (T=0.1-1.1 GK). ³⁹K; lifetime under novae conditions. Comparison to previous experimental data and statistical model predictions (SAPPHIRE and NON-SMOKER codes). Single coaxial HPGe detector surrounded by BGO anti-Compton shield at 5U Pelletron accelerator of the Nuclear Science Laboratory (University of Notre Dame).
