review text: Perturbation by unbounded potentials and corresponding eigenvalues are studied in the general framework of harmonic spaces. The results are applied to the Schrödinger equation \((\Delta -\mu)u=0\) on domains U in \({\mathbb{R}}^ n\), where \(\mu\) is a signed measure on \({\mathbb{R}}^ n\) such that \(\mu\) does not charge polar sets and \(\mu^-\) generates a finite potential.
