It is shown that the operator p2 \_ q2 has a continuous spectrum extending from --00 to + oo. The expansion of an arbitrary function with respect to the eigenfunctions is given. The action of the operators q and p on the eigenfunctions can be written explicitly by means of symbolic formulae. Finally
