Mean lifetimes of levels in 38Ar have been measured using the Doppler-shift-attenuation (DSA) method and the reaction 37Cl(p, γ)38Ar. The lifetime values or limits were determined for 37 bound levels below the excitation energy of 9 MeV; the lifetimes of 9 levels, upper limits of 2 and lower limits of 3 levels are reported for the first time. For the effective stopping of recoils, the targets were prepared by implanting 37Cl into Ta backings. The Monte Carlo method and the experimental stopping power were used in the DSA analysis.
