Abstract We extend the theorem of Balslev and Combes on the absence of singular continuous spectrum to a class of interactions includingr −α(3/2≦α〈2) local potentials. In addition, we note that the theory of sectorial operators allows a simplification of their proof and allows one to push the cuts through angles larger than the π/2 restriction employed by Balslev-Combes.
