Fig. 23.4 Three dimensional plot of -C(a,012) with Z = 1 in hyperspherical coordinates the ordinates represent a potential surface in Rydberg units at Rh = la0 (from ref. 11).

For a solid or molecule subdivided into atomic cells, the Poisson equation, given in Rydberg units by... 

A factor -2 included in the last term here compensates for the use of Rydberg units and for the omission of the negative electronic charge in potential functions derived from Eq. (7.14). Hence the electrostatic multipole moments of atomic cell r/( are... 

For energy k2 in Rydberg units, the Green function of the Helmholtz equation, with given boundary conditions, satisfies... 

Fig XXI-1.— Energies of electrons in the copper atom, in Rydberg units, us a function of principal quantum number n. Eneigies are shown on a logai ithmie scale. The energies in the hydrogen atom are shown for comparison. 

Figure 2. The change in the energy of the center of the 4f bands tf and in the band widths Ff as a function of the electron dynamic effective mass m+- in Y-cerium metal. Energy in Rydberg units. For m+./m > 1 the state becomes almost atomic like, and the f bands for different J = L + S values do not overlap in energy, AE3l F...

Table 5.1. Binding energies of the first EM even-parity donor states for 7 < 1 in effective Rydberg units [13]...

Here Vion(r) is the potential from the ions, and the atomic Rydberg units (e /2 = 2m = 5 = l) have been used in all the formulas. Since Eqs. (8) and (9) are explicitly defined in terms of the electron charge density, all approximations are applied to the last term in Eq. (7), the exchange and correlation energy.
