On the basis of results previously obtained, examples are illustrated according to which the one-dimensional self-adjoint Schrödinger and Dirac operators are shown to admit a point spectrum filling the half-axis (0,\(\infty)\) and the complete axis R, respectively. Examples in which the point spectrum fills only the interval (0,C), \(C>0\), are also given. Various theorems and lemmata are proved correspondingly.
