Variational estimates of the energy of excited states

摘要: The energies of excited states for two- and three-particle systems with arbitrary blocking potential are calculated within the framework a naive variational approach. uncertainty in calculation energy lower is comparable ground state all cases much less than 1%. highly found help approach classical limit: true functional dependence on quantum numbers reproduced errors order 1% numerical coefficients asymptotic expansion. principle time-averaged Hamiltonian periodic motions fixed action discussed. 14 refs., 5 tabs.
