We discuss some features of non-self-adjoint Hamiltonians with real discrete simplespectrum under the assumption that the eigenvectors form a Riesz basis of Hilbertspace. Among other things, we give conditions under which these Hamiltonians canbe factorized in terms of generalized lowering and raising operators.
