Abstract
We calculate numerically a few terms of the corrections to the large-order behavior of the ground state energy of the O(N) anharmonic oscillator by analyzing the perturbation series. We then generate 94 terms of the perturbative expansion of the difference between the energies of the two low lying states of the double-well potential and analyze their large-order behavior.Keywords
