Describe the Coulomb potential figure below with more
details
E4 0 -0.85 - 1.51 -3.39 E3 E2 Energy (EV) - 13.6 E1 V(r) Figure 7-3 The Coulomb potential V(i) and its eigenvalues En. For large values of n the eigenvalues become very closely spaced in energy since En approaches zero as n approaches infinity. Note that the intersection of vir) and Em, which defines the location of one end of the classically allowed region, moves out as n increases. Not shown in this figure is the continuum of eigenvalues at positive energies corresponding to unbound states.
