used to evaluate the remaining hydrogen concentrations di, d2, d4, and d. using (6.26). The uranium atom concentration C1 is then given by (6.23). The uranium ion concentrations are next calculated using equations (6.16-1) through (6.16-12). The hydrogen and uranium densities are given by (6.11) and the definition following (6.14-12), respectively.

        The electron density is still to be determined. Since a, , y, and H are functions of Ce, the expression (6.31) for d3 contains the electron concentration as an undetermined variable. The remaining hydrogen species and the uranium species are also functions of Ce, since they are determined by the value of d   For a specified pressure and temperature, the hydrogen, uranium and electron densities of the mixed plasma are uniquely determined. The proper value of Ce is determined by application of the mixing ratio definition (6.1), which has not been included in the derivation of equation (6.27). From solutions of the coaxial flow hydrodynamic equations or from measured density profiles obtained from plasma flow experiments, the mixing ratio is specified at each point in the mixing region. From (6.1), the mixing ratio is given by
