摘要：

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 Sm-154 + O-16. 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 Sm-154 and models using significantly different distributions cannot reproduce the measured excitation functions.
