Studies of rp-process nucleosynthesis in stellar explosions show that establishing the lowest l = 0 and l = 1 resonances is the most important step to determine reaction rates in the astrophysical rp– process path. In an experiment performed at the resolut radioactive beam facility of Florida State University, we studied the 25Al(d,n)26Si reaction in inverse kinematics to establish the spectrum of the lowest l = 0 and l = 1 resonances. We observed 4 resonances in 26 Si at 5923 keV, 6357 keV, 6737 keV, and 7458 keV. We establish the lowest l = 0 resonance at 5.923 keV, 0.409 MeV above proton separation. The result is consistent with the previous experiment performed at FSU by Peplowski et al. however now with significantly larger statistics and detection of the heavy ion decay in coincidence with the proton. We determine upper and lower limits on Γ p and calculate the astrophysical reaction rate. We establish the proton density and temperature conditions in which galactic through the 25Al(d,n)26Sireaction path.
