Abstract
For an operator, A, with cyclic vector phi, we study A + lambdaP, wher e P is the rank one projection onto multiples of phi. If [alpha, beta] subset-of spec(A) and A has no a.c. spectrum, we prove that A + lambd aP has purely singular continuous spectrum on (alpha, beta) for a dens e G(delta) of lambda's.
