For comparison, Tables 3 and 4 show discrete electronic states for the Coulomb potential of the charged sphere (1) for Z =1 and Z = 5, respectively.
The Nagaoka potential used to describe the kinetics of particles in the atom is the Coulomb potential of a geometrical point center of the atom that is given by V(r) = E/r, where r is the distance from the point center and E is a positive charge of the center.
In the scattering matrix theory, the analysis is carried out over the infinite distances from the interaction region both for initial and final states of the system, so that the incoming and outgoing wave functions are plain waves over the whole continuum, and in the derivation of (17), the integral for the Fourier component of the infinite range Coulomb potential is taken from 0 to [infinity].
During the process of emission and retrapping, the electrons meet a potential energy [phi](x) that is the superposition of the Coulomb potential of the emitting site and the Coulomb potential of the retrapping one, and given by
In the first case, substituting the radial part of potential as Coulomb potential in (13) [26, 27],

We can understand it very well by studying the contributions of the potential parameter b made on the Coulomb potential. The choice of the negative or positive b determines the attractive Coulomb potential that is bigger or smaller relatively.
