    "abstract": "High precision measurements of the fusion excitation functions for the\nreactions ^{40}Ca + ^{194}Pt, ^{192}Os clearly demonstrate that projectile\nexcitation significantly modifies the potential barrier distribution. In sharp\ncontrast, fusion of ^{16}O + ^{144}Sm appears to show no influence of the\nprojectile excitation on the shape of the barrier distribution. These\napparently conflicting conclusions are reconciled in this work, using realistic\ncoupled--channels calculations, which show that high energy states produce an\nadiabatic potential renormalisation. This result indicates that adiabatic\neffects restrict, in a natural way, the states which influence the shape of a\nfusion barrier distribution. The analysis of barrier distributions thus offers\na criterion for the relevance of the `counter term\u0027 prescription in the\nCaldeira-Leggett approach.",
