For an H-atom in a spherical box with variable radii R it is shown that the energy and the ESR-splitting constant for the groundstate calculated with a difference-hamiltonian are in good agreement with the results obtained by other methods. The dependence of the energy on the number n of discrete points and their distance for a given radius R is considered.
