Add to ORKGLet A be a selfadjoint operator in a Hilbert space aleph with inner product [.,.]. The rank one perturbations of A have the form A+tau [.,omega]omega, tau epsilon R, for some element omega epsilon aleph. In this paper we consider smooth perturbations, i.e. we consider omega epsilon dom \A\(k/2) for some k epsilon N boolean OR {0}. Function-theoretic properties of their so-called Q-functions and operator-theoretic consequences will be studied.</p
