摘要:

The variational method is applied to the problem of acxnpotential within an infinite one‐dimensional well. Approximate ground‐ and excited‐state wavefunctions are constructed as linear combinations of two‐term even and odd polynomials. Comparisons are made between calculated approximate wavefunctions and energies, and results predicted from perturbation theory and from the behavior of related systems.
