- W2372450062 abstract "We apply the improved variational-integral perturbation method to solve the quartic anharmonic oscillator in the first excited state.Setting the female Hamiltonian including variational parameter as the zeroth-order Hamiltonian and choosing the exact solution of the female Hamiltonian system as the trial wave function,we obtain the multi-order corrected wave functions consisting of a few terms and calculate the multi-order energy corrections.Comparison with the results of other method,the former are quadratically integrable and the latter are in good agreements with the exact data.The boundedness and convergence of the perturbation series solution are also verified.The results show that the variational-integral perturbation method can not only raise precision of the result but also keep convergence of the perturbation series." @default.
