Abstract: In the recent years a generalization of Hermiticity was investigated using acomplex deformation H=p^2 +x^2ix^\epsilon of the harmonic oscillatorHamiltonian, where \epsilon is a real parameter. These complex Hamiltonians,possessing PT symmetry the product of parity and time reversal, can have realspectrum. We will consider the most simple case: \epsilon even. In this paperwe describe all self-adjoint Hermitian and at the same time PT symmetricoperators associated to H=p^2 +x^2ix^\epsilon. Surprisingly it turns out thatthere are a large class of self-adjoint operators associated to H=p^2+x^2ix^\epsilon which are not PT symmetric.
