Using a 33 MeV proton beam with our Enge split-pole spectrograph, we measured the Q0 values of the 24Mg(p,t)22Mg and 28Si(p,t)26Si reactions relative to that of the 16O(p,t)14O reaction. Data were obtained at scattering angles of 15° and 25°. Based on the masses of 24Mg, 28Si, 16O, 14O,p, and t, we determined the mass excesses of 22Mg and 26Si to be −400.5(1.0) and −7139.5(1.0) keV, respectively. Our result for the mass of 22Mg is in excellent agreement with recent high-precision measurements.
