Abstract

Additional experimental information concerning the level structure of ²⁶Si above the proton threshold is needed to reduce uncertainties in the ²⁵Al(p, γ)²⁶Si reaction rate and consequently better determine ²⁶Al radioisotope production in astrophysical environments. The ²⁴Mg(³He,n)²⁶Si reaction was measured and excitation energies of states in ²⁶Si were determined with improved accuracy. Spins were assigned to a number of states by comparing their measured differential cross sections with Hauser-Feshbach cross sections. The 3⁺ resonance state of the ²⁵Al(p, γ) ²⁶Si reaction was identified at 5912(4) keV excitation energy and the ²⁵Al(p, γ)²⁶Si reaction rate in explosive hydrogen burning environments was calculated.
