As atom/molecule is exposed to an external electric field, it can be ionized. Besides, the energy of the atomic/molecule system is altered due to the influence of the atom/molecule – electric field interaction. The hydrogen atom is one of the simplest system to explore and is in current attention. In this paper, we numerically calculate the dependency of the energy of the hydrogen atom in arbitrarily excited states, including all degenerating states. The results are validated using second order perturbation theory.
