There exist (CO) semigroups Ti(t), T2(t) on Hilbert space with the following properties: li has a bounded generator and is uniformly bounded, but is not similar to a contraction semigroup. T2 is uniformly bounded, and there exists no scalar a such that e` T2(t) is similar to a contraction semigroup.
