Mean lifetimes have been measured by the Doppler shift attenuation method for several nuclei in the s-d shell. Both Ge(Li) and NaI(Tl) detectors were used. The results (in ps) for the energy levels indicated in parenthesis (MeV) were: <sup>24</sup>Mg(1.37)2.07+or-0.34, (4.23) 0.110+or-0.026; <sup>30</sup>Si(2.23)0.332+or-0.021, (3.51) 0.063+or-0.0015; <sup>34</sup>S (2.13) 0.467+or-0.090, (3.30) 0.144+or- 0.028; <sup>38</sup>Ar (2.17) 0.473<sub>-0.110</sub><sup>+0.145</sup>, (3.38) 25 <sub>-12</sub><sup>+ infinity </sup>, <sup>40</sup>Ar(1.46) 2.45 <sub>-1.30</sub><sup>+18</sup>.
