Abstract

Additional experimental information concerning the level structure of ${}^{26}{Si}$ above the proton threshold is needed to reduce uncertainties in the ${}^{25}{Al} (p, γ) {}^{26}{Si}$ reaction rate and consequently better determine ${}^{26}{Al}$ radioisotope production in astrophysical environments. The ${}^{24}{Mg} ({}^{3}{He}, n) {}^{26}{Si}$ reaction was measured and excitation energies of states in ${}^{26}{Si}$ 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 ${}^{25}{Al} (p, γ) {}^{26}{Si}$ reaction was identified at $5912 (4) keV$ excitation energy and the ${}^{25}{Al} (p, γ) {}^{26}{Si}$ reaction rate in explosive hydrogen burning environments was calculated.
