Fig. 2

Plots of Eqs. (12) and (13) as a function of γϵj are shown by the solid red and dashed blue lines respectively. The values of Sj and ϵN′/N′ have arbitrarily been chosen to be equal to 0.2 and 0.01/100 respectively. The solution we require is where Eq. (12) is equal to Eq. (13), which corresponds to γϵj = 21.467.
