Consider the case of a symmetrical double well, such as the one pictured in Figure 8.13. We are interested in bound states with E < V(0).

(a) Write down the WKB wave functions in regions , and . Impose the appropriate connection formulas at xi and x2 (this has already been done, in Equation 8.46, for x2; you will have to work out x1 for yourself), to show that
