Mean lifetimes of levels in 24Mg have been measured using the Doppler-shift-attenuation (DSA) method in conjunction with the reactions 23Na(p, γ)24Mg and 12C(14N, pn)24 Mg. The lifetime values or limits were determined for 27 bound levels below the excitation energy of 11 MeV; the lifetimes of 3 levels are reported for the first time. For the effective stopping of recoils, the targets were prepared by implanting 23Na and 12C into Ta backings. The Monte Carlo method and the experimental stopping power were used in the DSA analysis. The experimental transition strengths are compared with recent shell-model calculations.
