A surface for an @[email protected] A + BC in which the col corresponds to considerable separation between the products A–B + C. The energy barrier in the @[email protected] is in the later stages of the @[email protected] On such a surface most of the energy is released after A–B is formed. Repulsive surfaces are also called late-downhill surfaces, and the barrier in such a surface is called a Type-II barrier.
