In Fig. 4 (a) a surface plot of the energy coefficient m from equation (25) vs. ε and p is shown. A value of m > 1/2 is possible for low values of p (p→0) and large values of ε (ε→1).Another plot of m versus ε and p, for α = 0.75, is shown in Fig. 4 (b) where one can clearly see that m > 1/2 is also possible and even in a wider range of ε and p.
