Indirect study of the stellar ³⁴Ar(α, p)³⁷K reaction rate through ⁴⁰Ca(p, t)³⁸Ca reaction measurements

NUCLEAR REACTIONS ⁴⁰Ca(p, t)³⁸Ca, E=100 MeV; measured spectra using the K=600 magnetic spectrograph, triton spectra at K=200 Separated Sector Cyclotron facility of iThemba LABS. ³⁸Ca; deduced levels, α-unbound states, resonances, α-spectroscopic factors. Comparison with previous experimental results. ³⁴Ar(α, p)³⁷K, T₉=0.2-3.0; deduced reaction rates as a function of stellar temperature, and compared with theoretical model calculations using NON-SMOKER-v5.0w and TALYS 1.8 codes. Relevance to type I x-ray bursts (XRBs).
