The Doppler Shift Attenuation Method has been used to measure lifetimes for levels in 38 K at excitation energies of 1698, 2404, 2830, 2996 and 3671 keV, populated using the 40 Ca(d,α) 38 K reaction at a beam energy of 4.5 MeV. Values of 109 (29), 95(22), 457(63), 130(40) and 160(50) fs respectively were measured and are compared with previous values obtained using different stopping powers. The matrix element for the transition between the J π = 2 + T =1 and 0 + T =1 states in this T z =0
