The physical nature of low-lying energy levels of anharmonic oscillators is shown to be due to quantum reflections on (multiple) complex turning points. Mathematically, certain Stokes' lines linking complex-conjugate turning points may cross the real axis within the classically allowed region at poi
A procedure is described for extracting the dominant behavior at high energies of individual Feynman diagrams. This procedure is illustrated by the calculation of several examples, and is applied to the summation of several classes of diagrams in the high energy limit. Although all the examples deal
