Abstract
Using the method of point canonical transformation, we derive some exactly solvable rationally extended quantum Hamiltonians which are non-Hermitian in nature and whose bound state wave functions are associated with Laguerre- or Jacobi-type exceptional orthogonal polynomials. These Hamiltonians are shown, with the help of imaginary shift of co-ordinate: , to be both quasi and pseudo-Hermitian. It turns out that the corresponding energy spectra is entirely real.
