| Abstract : | A simple, one-parameter Hamiltonian decomposition is discussed that modifies the convergence rate of perturbation expansions and converts diverging into converging series. Two upper bound expressions an used to monitor the resulting series. The x(2) and x(4) potentials are studied as illustrations of this technique. (C) 2000 American Association of Physics Teachers., |
