Query: A method on generation of finite level(s) in real and complex systems
  using R potential   We generalize R model approximation to generate finite energy level(s)
quantum systems in both h and non-Hermitian quantum systems. In h systems, it
has been applied to a wide range of bounded single well, triple well and pentic
well systems. Apart from this spectral Hermitian systems have been considered.
F model has been extended to PT-symmetric systems under spectral condition.
