Astrophysically important {sup 26}Si states studied with the ({sup 3}He,n) reaction and the {sup 25}Al(p,{gamma}){sup 26}Si reaction rates in explosive hydrogen burning environments

Journal Article · · Physical Review. C, Nuclear Physics
Additional experimental information concerning the level structure of {sup 26}Si above the proton threshold is needed to reduce uncertainties in the {sup 25}Al(p,{gamma}){sup 26}Si reaction rate and consequently better determine {sup 26}Al radioisotope production in astrophysical environments. The {sup 24}Mg({sup 3}He,n){sup 26}Si reaction was measured and excitation energies of states in {sup 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{sup +} resonance state of the {sup 25}Al(p,{gamma}){sup 26}Si reaction was identified at 5912(4) keV excitation energy and the {sup 25}Al(p,{gamma}){sup 26}Si reaction rate in explosive hydrogen burning environments was calculated.
