Complex eigenvalue Schrodinger equation CESE

This question was answered some time ago in Ref. [101], where we showed how the corresponding complex eigenvalue Schrodinger equation (CESE) is derived via the appropriate consideration of boundary condifions. The concomitant results justify the computation of resonance sfafes in ferms of non-Hermitian, complex-energy formalism via fhe use of superposifions of square-integrable real and complex funcfions. 

For example, this form is in harmony with the superposition of energy states in Eq. (2), whose coefficients have been obtained formally by Fano [29]. Although, for the solution of particular problems involving unstable states, we have implemented, in conjunction with the methods of the SSA, the real-energy, Hermitian, Cl in the continuum formalism that characterizes Fano s theory, e.g.. Refs. [78, 82-87] and Chapter 6, in this chapter I focused on the theory and the nonperturbative method of solution of the complex eigenvalue Schrodinger equation (CESE), Eq. (27).
