One-proton breakup of ²⁴Si and the ²³Al(p, γ)²⁴Si reaction in type I x-ray bursts

NUCLEAR REACTIONS ¹²C(²⁴Si, X)²³Al, [²⁴Si secondary beam from C(³²S, X), E=95 MeV/nucleon primary reaction], E=61 MeV/nucleon; measured fragment spectra, σ, inclusive longitudinal momentum distribution, time-of-flight of ²³Al fragments using SPEG spectrograph at GANIL; deduced spectroscopic factors, asymptotic normalization coefficient (ANC). Glauber-type analysis. Comparison with large-scale shell model calculations. ²³Al(p, γ)²⁴Si, E<1 MeV; deduced stellar reaction rates. Discussed astrophysical significance of ²³Al(p, γ)²⁴Si in type I x-ray bursts (XRB) nucleosynthesis. Waiting-point nuclei and relevance to ²²Na abundance and sequential 2p capture on ²²Mg at high temperature.
