Fusion probability of colliding heavy ions is evaluated by exactly solving a Langevin equation with a parabolic potential barrier. The model, which accommodates dissipation in the approaching phase, leads to an inverse Kramers formula and an expression of the extra-push energy. In the very specific case of an overdamped regime, an Arrhenius-type formula is obtained.
