    From the partial differential Calogero's (three-body): and Smorodinsky-Wintemitz (superintegrable) Hamiltonians in two variables we separate the respective angular Schrodinger equations and study, the possibilities of their 'minimal' PT symmetric complexification.. The simultaneous loss of the Hermiticity and solvability of the respective angular potentials V(phi) is compensated by their replacement by solvable, purely imaginary and pieced wise constant multiple wells V-0(phi). We demonstrate that the spectrum remains real and that it exhibits a rich 'four series' structure in the double-well case

    Ukázáno, že komplexifikované a vhodně aproximované verze calogerovských a winternitzovských modelů vykazují reálná spektra s bohatší strukturou. Numericky ilustrováno na nejjednodušším netriviálním příkladě se čtvernou substrukturou spektra.
