We study the existence of solutions of the Dirichlet problem for the Schrödinger operator with measure data. We characterize the finite measures for which such a problem has a solution for every nonnegative potential in Lebesgue spaces. The full answer can be expressed in terms of a capacity. We then investigate the existence of a solution of the problem above when the potential belongs to the real Hardy space.
