A new semiclassical mechanism of multi-dimensional tunneling, which originates in the complexified stable and unstable manifolds of the unstable saddle (or unstable periodic orbit) on top of the potential barrier, causes a remarkable plateau-like structure in the tunneling spectrum. Such a mechanism is very universal and works when the instanton mechanism breaks down due to the strong coupling between the degrees of freedom.
