Direct measurement of astrophysically important resonances in ³⁸K(p, γ) ³⁹Ca

NUCLEAR REACTIONS ¹H(³⁸K, γ)³⁹Ca, E=15.58, 20.56, 27.17 MeV, [³⁸K secondary beam produced at ISAC-I, TRIUMF facility by impinging 500 MeV protons on a high-power TiC production target]; measured recoils using DRAGON spectrometer, prompt Eγ, Iγ, (recoil)γ-coin using bismuth-germanate scintillator array for γ detection. Windowless hydrogen gas target; deduced energies of resonances, resonance strengths for the 386-, 515- and 689-keV proton resonances, astrophysical reaction rates for temperature range of 150-500 MK, abundances of ³⁸Ar, ³⁹K, and ⁴⁰Ca in the hottest oxygen-neon novae.
