    "abstract": "We investigate the effect of anharmonicity on the WKB approximation in a\ndouble well potential. By incorporating the anharmonic perturbation into the\nWKB energy splitting formula we show that the WKB approximation can be greatly\nimproved in the region over which the tunneling is appreciable. We also observe\nthat the usual WKB results can be obtained from our formalism as a limiting\ncase in which the two potential minima are far apart.",
