We investigate in what regime of the frequency the new tunnelingmechanism using unstable and stable manifolds of dividing saddle(K.Takahashi &K.S.Ikeda, J.Phys.A. 41 (2008) 095101; Phys.Rev.A, 79 (2009) 052114) works asthe leading mechanism of multi-dimensional barrier tunnelling. In the large andsmall limits of the frequency, the tunneling rate is well evaluated based on theinstanton picture. It is in the intermediate frequency range that the new mechanismdominates the tunneling process. The tunneling rate takes the maximum value in thisintermediate range.
