Abstract: | Mean lifetimes of levels in 26Al have been measured using the Doppler-shift attenuation (DSA) method and the reaction 25Mg(p, γ)26Al. The lifetime values or limits were determined for 34 bound levels below the excitation energy of 6 MeV; the lifetimes of 13 levels and upper limits of 3 levels are reported for the first time. For the effective stopping of recoils, the targets were prepared by implanting 25Mg into Ta backings. The Monte Carlo method and the experimental stopping power were used in the DSA analysis. |
