"We show that the potential wells with a central spike V(x)=x operator (10) + a x operator 8 + b x operator 6 + c x operator 4 + d x operator 2 + f/x operator 2 possess arbitrary finite multiplets of elementary exact bound states. The strong asymptotic growth of V(x) implies an ambiguity inthe PT-symmetric quantization via complex boundary conditions but the three eligible recipes coincide at our exceptional solutions." . .
