Different approach to the Stark effect: application to the excited states or hydrogen atom

The application of a semi-analytical method introduced by the present authors in a previous work has enable us to calculate the excited energy levels and wave functions associated with the Stark effect on a Hydrogen atom. The method is a variational one and we used algebraic computation to solve it. We present the results to the n = 2 and n = 3 levels. It is shown that in these cases the method works as well as it does for the ground state. On the other hand the wave functions associated with the stationary states show the probability of autoionization by tunneling in the limit of high fields. (author). 18 refs, 3 figs, 6 tabs
