A mean lifetime measurement has been carried out on the states in the superdeformed band found in <sup>131</sup>Ce using the Doppler shift attenuation method (DSAM). The measured intrinsic nuclear quadrupole moment is Q<sub>0</sub> approximately=6 eb, assuming constant deformation, which corresponds to a quadrupole deformation beta <sub>2</sub> approximately=0.35. This is considerably smaller than the value deduced for <sup>132</sup>Ce.
