    "abstract": "Symmetric heavy-ion collisions are known to display an `extra-push\u0027 effect.\nThat is, the energy at which the s-wave transmission is 0.5 lies significantly\nhigher than the nominal Coulomb barrier. Despite this, however, the capture\ncross section is still greatly enhanced below the uncoupled barrier. It is\nshown that this phenomenon can be simply explained in terms of entrance-channel\neffects which account for long-range Coulomb excitations.",
