This paper is dedicated to the memory of Professor B. Jouvet who saw clearly the close connection between renormalizable theories like the Lee model and the nonrenormalizable four-spinor interaction at a time when most physicists would not seriously entertain even the possibility. ABSTRACT. It is possible to have discrete normalizable eigenstates of energy with eigenvalues overlapping the continuous spectrum. A simple collection of examples exhibiting this behaviour is presented in this paper.
