It has been argued long ago that {eta}{sub b} could be observed through the {eta}{sub b}{yields}J/{psi}({yields}{mu}{sup +}{mu}{sup -})J/{psi}({yields}{mu}{sup +}{mu}{sup -}) decay chain. Recent calculations indicate that the width of {eta}{sub b} into two J/{psi} is almost three order of magnitude smaller than the one into the DD*. We study the effects of final state interactions due to the DD* intermediate state on the J/{psi}J/{psi} final state. We find that the inclusion of this contribution may enhance the short distance branching ratio of about two orders of magnitude.
