Phys. Rev. Lett. 79, 2014–2017 (1997)Adiabatic Quantum Tunneling in Heavy-Ion Sub-barrier FusionReceived 10 February 1997; published in the issue dated 15 September 1997 The measured fusion barrier distributions for 40Ca+192Os, 194Pt show significant features due to projectile excitation, while none are seen for 16O+144Sm. This conflict is reconciled using realistic coupled-channel calculations, which show that the higher excitation energy of the 3- state in 16O produces an adiabatic potential renormalization, without affecting the structure in the barrier distribution. This result indicates that adiabatic effects restrict, in a natural way, the states which influence the shape of a fusion barrier distribution. © 1997 The American Physical Society URL:
