The commonly held view that fusion excitation functions are featureless and do not provide a good test of models is challenged by high-precision measurements for the reaction {sup 154}Sm+{sup 16}O. The data yield a well-defined distribution of barrier heights using a recently proposed, novel analysis technique. The measured distribution is that expected from the quadrupole deformation of {sup 154}Sm and models using significantly different distributions cannot reproduce the measured excitation functions.
