    "abstract": "Within the framework of the recently proposed formalism using non-hermitean\nHamiltonians constrained merely by their PT invariance we describe a new\nexactly solvable family of the harmonic-oscillator-like potentials with\nnon-equidistant spectrum. Our one-dimensional superposition of the harmonic x^2\nwith the centrifugal-like G/x^2 is regularized by a purely imaginary shift of\n$x$.",
