(a) Relative electron densities, in which the densities are normalized to that of ambient air, x = 20 mm. (b) Estimated temperature distribution. The x dependences are measured at the position y = 5 mm. The positions x and y are defined in Fig. 1(b). Closed circles denote the temperature by the present Compton scattering measurements (CP) and open squares by thermocouple measurements (TC). The combustion reaction zone is at |x| = 4.5 mm. |
