    "abstract": "Using a method of local transmission matrix, we generalize the well-known WKB\nformula for a barrier penetrability to multi-channel systems. We compare the\nWKB penetrability with a solution of the coupled-channels equations, and show\nthat the WKB formula works well at energies well below the lowest adiabatic\nbarrier. We also discuss the eigen-channel approach to a multi-channel\ntunneling, which may improve the performance of the WKB formula near and above\nthe barrier.",
