โœฆ Synopsis


Energy levels for double-well potentials in one-, two-, and threedimensional systems are calculated using the Hill determinant approach for several eigenstates and large values of the perturbation parameters (, Z 2

x , Z 2 y , Z 2 z ). Numerical results for some special cases agree with those of previous workers where available. แฎŠ 1996 Academic Press, Inc.

We introduce a generalization of Wick-ordering which maps the anharmonic oscillator (AO) Hamiltonian for mass m and coupling h exactly into a "Wick-ordered" Hamiltonian with an effective mass M which is a simple analytic function of h and m. The effective coupling rl = X/M3 is bounded. We transform
