Parity times time-reversal symmetry of complex Hamiltonians with real spectra is usually interpreted as a weaker mathematical substitute for Hermiticity. Perhaps an equally important role is played by the related strengthened analyticity assumptions. In a constructive illustration we complexify a few potentials solvable only in s-wave. Thenwe continue their domain from semi-axis to the whole axisand get the new exactly solvable models. Their energies come out real as expected. The new one-dimensional spectrathemselves differ quite significantly from their s-wave predecessors.
