Abstract
In this paper we study the decomposability of rank one perturbations of complex symmetric operators R = T + u circle times v. Also we investigate some conditions for which R satisfies a-Weyl's theorem. Finally, we characterize some conditions for R to be hyponormal. As consequences, we provide several cases for such operators.
