Abstract
We calculate the free interaction energy of two finite-temperature nuclei in the sudden approximation by using realistic semiclassical energy-density functionals. The fusion barriers for intermediate-size systems come over their ground state values for higher temperatures in such a way that there is a ‘‘critical temperature’’ above which fusion cannot occur. We discuss the implications of our results for the interpretation of empirical data.Keywords
