A method on generation of finite level(s) in real and complex systems

The Rath's mannequin approximation is generalized in this work to generate finite strength level(s) quantum structures in Hermitian and non-Hermitian quantum systems. On one hand, in Hermitian systems, an extensive variety of bounded single properly,triple nicely, and pentic proper systems is utilized. On the other hand, isospectral Hermitian structures are considered. Further mannequin is extended to PT-symmetric structures involving an isospectral condition.
