    "abstract": "The aim of this paper is twofold. First of all, we study the behaviour of the\nlowest eigenvalues of the quantum anharmonic oscillator under influence of an\nexternal field. We try to understand this behaviour using perturbation theory\nand compare the results with numerical calculations. This brings us to the\nsecond aim of selecting the best method to carry out the numerical calculations\naccurately.",
