Phys. Rev. C 70, 065805 (2004) [9 pages]Astrophysically important 26Si states studied with the (3He,n) reaction and the 25Al(p,γ)26Si reaction rates in explosive hydrogen burning environmentsSee Also: Erratum Received 29 September 2004; published 20 December 2004 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. © 2004 The American Physical Society URL:
